High PRF helps spot targets moving towards you. Low PRF helps see targets beaming or moving away from you. I'd say High PRF is more useful, you have a much longer range against targets moving towards you and a much shorter timeframe to engage fast moving targets. Low PRF has its uses but I tend to dramatically less than high. Also targets moving towards you have a good chance to be aggressive, and you have a far shorter IRST range whilst targets moving away you are normally the aggressor, IRST can usually lock, you're often still wanting to have an awareness of targets attacking you (changing PRF has a very severe effect on your range), and quite often you'd want to remain stealthy and can turn the radar off entirely. That said TWS only works with PRF high or low (I believe the F-15C can still use mixed) and so at least being aware of its capabilities is useful. As for the Russian radars, they scan 60 degrees wide, the same as the reduced scan area of the F-15C. Usually it scans 30 degrees left, 30 degrees right. By shifting it you can scan from 60 left to 0, or from 60 right to 0. The F-15C allows you to slew in gradual steps. Also it appeared that when focusing a target in TWS the radar slewed to center on the enemy target, something which it wasn't able to do when I last played. Also the F-15C is able to use TWS whilst facing enemy jammers and the Su-27 switches back to RWS. Unfortunately the F-15C isn't able to scan 120 degrees whilst in TWS whilst it was able in FC2, but shifting to a smaller scan zone is usually a good idea anyway regardless of scanning mode, particularly when you know an enemy is going to be appearing from a certain direction. So even with slewing the Su-27 isn't able to beat the F-15C in scan area, but I do believe that when using TWS the datalink sends targets to all friendlies in your flight (even online), if so you can use advanced tactics to utilise that. Having one pair sitting at range using TWS and covering a huge area of sky would allow the other pair to fly in with IRST and datalink and engage enemies from behind the mountains with IR missiles before returning back behind cover. With advanced tactics the Su-27 can be incredibly dangerous, and I was very sad when they removed the datalink from the Mig-29 (with its active and/or large number of passives). The F-15C can mad dog and carry far more missiles sure, but a Su-27 with datalink and IRST has far more situational awareness and can launch guided missiles without requiring luck. The Mig-29 retains the lock, gets even more R-27D shots (and actives), but with no datalink it needs some hand holding from GCI to properly hide behind mountains and take a sneak shot, as it was apparently designed to do.
Very comprehensive, well done. Although, as I understood it, TWS mode requires interleaving PRFs because RWS is merely doing simple range reports and clutter rejection, so it's a simple question of timing the pulse returns and ignoring Doppler frequencies below a certain threshold. In TWS, however, you have to use that Doppler return to determine target velocity to help build a track file. This means digitally sampling the RADAR returns, and X band tactical RADARs have carrier frequencies in the 10s of GHz, which no computer can keep up with... without trickery. Essentially, the signal processing the fire control system does provides multiple range and velocity blips from a single target for a given PRF, and a different set of blips for another PRF. Find out where the blips for the two PRFs match up, and you've got your target found. From there, the track file starts getting built. Also, lower PRFs will give you a longer maximum tracking range, with the downside of a higher blind velocity (below this speed relative to ownship, the RADAR can't distinguish it from clutter). So if your target is slower relative to you (like notching or a slow forward aspect/nose cold), a higher PRF will allow you to pick it up, but at a shorter range. TL,DR: TWS uses both PRF types in an interleaved scan to accurately track targets, higher PRF is best for targets that are have a slow relative speed to you (notching or traveling close to the same speed as you nose-cold), although lower PRFs give you a higher tracking range.
It's been a while since I played dcs, but from my limited understanding, what that number on the bottom on the hud does corresponds to the elevation input displayed on the right; it automatically determines the angle at which the radar antenna needs to be pointed to scan a particular distance specified by that number. For example, you are flying at 2000m and AWACS says there a bandit 10km in front of you at an altitude of 12000m, you would set the predicted range to 10 (number on bottom of hud) and adjust the radar elevation to 10 on the right hand side (this number corresponds to 1000m intervals, I believe). If done correctly the center of the radar cone is pointing upwards at 45 degrees. If the target was 20km, 50km, 100km or 150km away, the corresponding angle of the radar would be approximately 26.5, 11, 5, and 3 degrees respectively, above the longitudinal axis of the aircraft. The scale on the right hand side also seems to move accordingly to the distance set (notice how it makes big movements at smaller ranges than at larger ones). This is the reason why if there is a bandit flying just below you or at your altitude, there's a chance tilting the radar up one increment will cause the bandit to disappear, because the bogey is just outside the radar cone detection range (assuming the number at the bottom of the hud is set to 10). it's a good rule of thumb to set that number at the bottom of the hud to something like 50km; if you're searching for a target, adjusting the radar elevation range will physically move the radar antenna at smaller angles ensuring you don't leave large gaps in your search area. If you set that number at the bottom to 150 and adjust the radar elevation, you'll notice the radar will only move and and down a small amount, because you're basically telling it to look for a target 150km out from you and at that distance the radar detection cone is much larger. Like this comment if this explanation is correct. I could be entirely wrong :\
I was only watching this video to find out what the number at the bottom means, just to find out at 13:20 that this little thing is omitted. After reading your last words "I could be entirely wrong" I turned to the manual to check - always should do that in the first place! The manual is really good and you can just grab it as pdf online. So you are right, if you know the target elevation and distance, you can use the "range angle method", which you described. One note: The radar elevation has to be set to the altitude *difference* between your plane and the target in km.

The OEPS-27K, however, provides more accurate data and generates less noise. *_source:_*_ Su-33 manual, p. 38 et seq._ While real data of the OLS-27 sensors are not available, since not officially disclosed, nonetheless acquirable data seem to differ a lot, especially from the manual. E.g. they say the coverage would be -60° to +60° in azimuth (so far so identical), but -60° to +15° in elevation, which is a whole nother world compared to what the manual states (www.deagel.com/Sensor%20Systems/OEPS/a001912 and additional info at www.ausairpower.net/APA-Flanker.html#mozTocId288713). None of the provided data mean that they were and/or how it's even simulated in the game. The HUD's symbolic is already simplified, the real HUD looks different and provides more informations. Hence chances are, the functionality of the IRST/EOS is also simplified, if not even dumbed down for unbearable _'balancing'_ purposes, which would be a bit of a cheek in a simulation like this. So, take all of it with a pinch of salt. It required to be tested ingame, what is what. Or the devs would eventually provide us with solid informations about the ingame performance ..o.f. both the 27's and 33's IRSTs. They must know, if anybody. I have no real idea about the ingame mechanics either. I just use the system to the best extent I can, like shown in the vid. Just one more thing to mention as for 21:17 : don't be afraid to turn the radar on while already in IRST track mode (when the target is locked), it will still not trigger the adversary's RWS, it remains as stealthy as it was with radar off. So, you can perform your IFF check - should become mandatory for you - without risking to warn the target against your lock-on.
Thanks for great vid Cap. Slight correction: EO has very narrow vertical field of view and you CAN slew it vertically and horizontally. Since the vertical FOV is so low, you in fact have to slew it if you want to see anyting. Vertical slew is analog (you can map it to joystick axis) just like radar. Horizontal slew has 3 positions - left, center and right..again just like radar. Another advantage of EO is that it displays targets immediately - unike radar which has to complete its scan cycle before displaying any contacts. This means that you can slew the EO very violently and see your contacts right away.
Hey cap, as a ex aircraft technician in the military i have a great reference book on radars/EO/stores/databuses etc... Its publicly available. Military Avionics Systems by Ian Moir albeit its expensive but great for information for anyone in the field or just interested in this stuff
Really appreciate the time and effort you put into these videos. New to the game, I've yet to engage in any effective combat in DCS because I'm still in Grim Reaper combat training academy!
Yea man how disappoint 2nhear that. Its for doping your scope. To try to get a lock cause if you goin vs eagels. Well they prolli already got you hearing music... your rwrs music.
4:43 It's not the wingspan. It's (or at least it should be) RCS of the target as it is important for received signal strength. It's not only wingspan. MiG-21 has much lower wingspan than B-1B but has notably bigger RCS. MiG-21 is small plane but with huge (as for its size) RCS of 4 sq meters when head on (RCS varies depending on aspect). B-1B IIRC is closer to 1 sq meter (B-1A before modernization in contrast was like 10 or so). 5:40 Prioritization should be based on distance and relative speed IIRC. At least that how F-16 radar make it when there are more than 10 targets in TWS mode, the less important are dropped from track file and displayed like in RWS while the 10 most important ones make its way into trackfile. I think it gonna be similar here cause it is pulse doppler radar too.
But he explained it for both systems nonetheless: 18:26 It's just your lack of attention span not capacitating you enough to carefully watch and follow a video to grab all the given infos from it, combined with your laziness to not even be willing to check the keybindings of a particular module before you search for it on YT, let alone to RTFM. Maybe such games are too much for ya. Because they require much more skills to gather all available informations at any given moment than you're obviously capable of.
Essentially, yes, you're both right. The number 10 is the anticipated range of the enemy. The +1, +2 and -1, -2 is the anticipated elevation change of the target. Thus +1 is 1km higher (3,000 feet) at 10km range. Changing it to 50km range would be 1km higher at 50km range. So in effect it is as though it changed the step motor. 1km at 10km range is the same as 5km at 50km range (or 15,000 feet). Personally I would suggest using something more like 50km or 100km for the range number, 50km is a fairly reasonable estimation of range, and 100km is an easy number to work with. 50km also allows a decent slewing range, 30,000 feet at 50km or 6,000 feet at 10km. Personally I prefer to change the range and elevation independently, but I've got a good number of HOTAS keys and analogue controls so I'm fortunate there.
13:13 Elevation of the radar basically makes radar look 1 km above/down at the time. So, if target is 5 km above me, I set the elevation to 5 (as the manual says so). What about 10.0 (predicted range) , it is mostly used when bandit is using the radar jammer. AWACS or EWR provide information about him, and range is set to whatever it is (you have to lock the jammer, then set the predicted range so you know if you have LA or if out of range). Sometimes (I think) it can be used to detect the enemy on your own radar while you are provided with AWACS information (can be used with radar elevation, though sometimes it doesn't work, so better to leave on 10.0, finds enemy better). 19:09 Yes, you can) That is an issue for mig-29, he can't.
FYI: The Target Designator (U/D/L/R) sensor setting, in the keybind options area, is the same thing as the TDC Slew (Vert/Horiz) in axis commands. I asked that question on the forum and that is the response I got.
The IFF and datalink is so much an advantage against the f18 right now that it makes the game really unfair/ not even mentioning the IRST and tws mode..
The number at the bottom if i am remembering correctly is slew increment so when you move the dish it is moving 10 degrees you can change it to be more or less per move. I could be wrong been a while since i flew the flanker.
The number down the bottom is the predicted target range, the number on the right side represents the radar elevation in 1000m increments. The angle the radar antenna moves is directly related to the target range number; the larger the number, the smaller movement the antenna makes.
Scan Distance is what Key Stroke ? I cant find it ?? The lower right radar screen in your video shows an independent value for the "range" - I dont think I have seen that before ? Also what keystroke slews the radar cone right and Left . I used to know but cannot find it anywhere using any type of search ?
I still dont get how is the mighty ability of Su-27 and similar ACs stealth no-radar IR attack is done with radar turned off? And is the auto-lock targets simplification bugged or in what conditions it should work? Been trying to figure the whole day how to out-range the F-15s in the nevada training mission. I get 1-2 of them at close range and then eject...
Sorry for the question but, the action you're trying to do from 13:25 (Slewing) how is it called in the controll of the game? as i cannot find it at all. not knowing the name i cannot set a key :(
Looking for players wanted to team up for REDFOR side to play together in organised way (jTAC/AWACS/Fighter Pilots/Strike/Helicopters on SRS/discord) on DDCS dynamic caucasus server.
I have a question about the IFF system in DCS. How does it respond when interrogating something that (I assume) doesn't have an IFF transponder like a Spitfire? Am I right in assuming that it would tell you the Spitfire was unidentified/enemy regardless of if it was on your team?
Can you get bitching Betty in English instead of Russian? It’s kinda common sense what she’s saying, when you about to dive into the ground, but just wondering if there is an option for English.
Curious about EO -- Since there's no radar lock on the target, if you fire a semi-active or passive missile, such as an R-27ER, will your target receive missile warning? Or can you even fire that missile with EO lock?
If you try to launch R-27(E)R in EO lock, you will have to hold down the weapon-release button for longer, radar will turn automatically on, lock your EO target and thus he will receive warning.
+1 to Baron Nomis response, the R-27ER or other radar guided missiles will have to have a radar target to have launch authorization so they can't be launched with an EO lock. You could do an R-27ET launch with EO.
Why. On EARTH. Is something as fundamentally powerful and important as full Data Link modeling /not/ even a PRIORITY for the DCS devs, let alone in the game already? Data Link being fully modeled would change how every aspect of the sim goes. It would reward teamwork to a scale never seen before. How in the hell is this not a thing? Also, with the Radar superimposed on the HUD, if you want to use the radar cursor...which do you set as SOI? The Radar, or the HUD? Or....does the Su-27 even /have/ a SOI function given it only has one cockpit display at all.
got FC3 yesterday and try to understand the radar. what angle in front of the plane is covered by radar? or: do you _need_ to tilt the radar like he does @6:34?! im needed to do this always manual to find enemy planes? so many stuff to know :/ guess im going back to the 25t :)
Is high PRF useful when a target is trying to Doppler notch? Low PRF gives greater unambiguous range but is less sensitive to low-velocity targets. Perhaps high PRF would be useful when a target is trying to blend in using notching since it's likely to still have a little closing velocity. High PRF should also produce more energy on target.
I don't know the ins and outs but in general High PRF is better at detecting hot targets and Med/Low is better for flanking or cold targets. I would assume that if a target were trying to notch then switching off of High would help. I tend to use High almost exclusively, at least once I get a RWR alert, because I care more about hot targets than cold. That's probably a noob move but it seems to work most of the time.
Pretty much. Hot basically describes when they are pointed at you and cold is when they are pointed away. You could also say that when your bearing to them is less than 180° they are hot and if your bearing to them is more than 180° they are cold. It doesn't really matter if you're pointed at them or not but rather how they are pointed to or away from you.
5:01 How do you get that zoomed in on the HUD (or is that through editing?)? With my trackIR even if I put my face right next to the HUD the text/symbology stay the same size
You people flood TH-cam with your video game you should put in the title what your video entails you see I'm looking for real world radar footage of an sU 27 not your sim imaginary world and you see how aggravating this could be right
Yeah, it actually says DCS World in the title though I can understand one may not be familiar with this name. Anyway, you're very unlikely to find real world footage of the radar on any aircraft in active service.
You can actually datalink between flankers in DCS. your aircrafts must be set from the editor as lead and wingman. works like a charm.

None of the provided data mean that they were and/or how it's even simulated in the game. The HUD's symbolic is already simplified, the real HUD looks different and provides more informations. Hence chances are, the functionality of the IRST/EOS is also simplified, if not even dumbed down for unbearable _'balancing'_ purposes, which would be a bit of a cheek in a simulation like this.
So, take all of it with a pinch of salt. It required to be tested ingame, what is what. Or the devs would eventually provide us with solid informations about the ingame performance ..o.f. both the 27's and 33's IRSTs. They must know, if anybody. I have no real idea about the ingame mechanics either. I just use the system to the best extent I can, like shown in the vid. Just one more thing to mention as for 21:17 : don't be afraid to turn the radar on while already in IRST track mode (when the target is locked), it will still not trigger the adversary's RWS, it remains as stealthy as it was with radar off. So, you can perform your IFF check - should become mandatory for you - without risking to warn the target against your lock-on.
Thanks for that post, Claude! Tons of good stuff!
Thanks for great vid Cap. Slight correction: EO has very narrow vertical field of view and you CAN slew it vertically and horizontally. Since the vertical FOV is so low, you in fact have to slew it if you want to see anyting. Vertical slew is analog (you can map it to joystick axis) just like radar. Horizontal slew has 3 positions - left, center and right..again just like radar. Another advantage of EO is that it displays targets immediately - unike radar which has to complete its scan cycle before displaying any contacts. This means that you can slew the EO very violently and see your contacts right away.
Copy thanks
Just got DCS and SU-27 module for a few days, my biggest problem is with radar.. This helps alot, thanks man!
Me too! My first module actually (the 33)
Hey cap, as a ex aircraft technician in the military i have a great reference book on radars/EO/stores/databuses etc... Its publicly available. Military Avionics Systems by Ian Moir albeit its expensive but great for information for anyone in the field or just interested in this stuff
the JH
Really appreciate the time and effort you put into these videos. New to the game, I've yet to engage in any effective combat in DCS because I'm still in Grim Reaper combat training academy!
lol thx
The 10 in radar scan mode is the suspected range to target. It's used for accuracy as well as slew scale
Yea man how disappoint 2nhear that. Its for doping your scope. To try to get a lock cause if you goin vs eagels. Well they prolli already got you hearing music... your rwrs music.
Way more information than the in game tutorial great work, thanks
It's not a cake, it's a Quesadilla!!
this is cool :) been flying flankers for a while now and still learned something new from this.
Could you give me some advise about trimming? I'm desperate
4:43 It's not the wingspan. It's (or at least it should be) RCS of the target as it is important for received signal strength. It's not only wingspan. MiG-21 has much lower wingspan than B-1B but has notably bigger RCS. MiG-21 is small plane but with huge (as for its size) RCS of 4 sq meters when head on (RCS varies depending on aspect). B-1B IIRC is closer to 1 sq meter (B-1A before modernization in contrast was like 10 or so).
5:40 Prioritization should be based on distance and relative speed IIRC. At least that how F-16 radar make it when there are more than 10 targets in TWS mode, the less important are dropped from track file and displayed like in RWS while the 10 most important ones make its way into trackfile. I think it gonna be similar here cause it is pulse doppler radar too.
Very useful - there is always something new to be learned
i like the fact that you dont state how to actually turn on the radar in the first place...
just go to your settings, usually it is the "I" key when you are in bvr mode
But he explained it for both systems nonetheless: 18:26 It's just your lack of attention span not capacitating you enough to carefully watch and follow a video to grab all the given infos from it, combined with your laziness to not even be willing to check the keybindings of a particular module before you search for it on YT, let alone to RTFM. Maybe such games are too much for ya. Because they require much more skills to gather all available informations at any given moment than you're obviously capable of.
EO can be slew left and right but not up and down. Number 10 in center low part of HUD is expected range to target.
Essentially, yes, you're both right. The number 10 is the anticipated range of the enemy. The +1, +2 and -1, -2 is the anticipated elevation change of the target. Thus +1 is 1km higher (3,000 feet) at 10km range. Changing it to 50km range would be 1km higher at 50km range. So in effect it is as though it changed the step motor. 1km at 10km range is the same as 5km at 50km range (or 15,000 feet). Personally I would suggest using something more like 50km or 100km for the range number, 50km is a fairly reasonable estimation of range, and 100km is an easy number to work with. 50km also allows a decent slewing range, 30,000 feet at 50km or 6,000 feet at 10km. Personally I prefer to change the range and elevation independently, but I've got a good number of HOTAS keys and analogue controls so I'm fortunate there.
You can slew up and down just like radar. Even proportionally (by assigning joystick axis to it).
Copy to all
13:13 Elevation of the radar basically makes radar look 1 km above/down at the time. So, if target is 5 km above me, I set the elevation to 5 (as the manual says so).
What about 10.0 (predicted range) , it is mostly used when bandit is using the radar jammer. AWACS or EWR provide information about him, and range is set to whatever it is (you have to lock the jammer, then set the predicted range so you know if you have LA or if out of range).
Sometimes (I think) it can be used to detect the enemy on your own radar while you are provided with AWACS information (can be used with radar elevation, though sometimes it doesn't work, so better to leave on 10.0, finds enemy better).
19:09 Yes, you can) That is an issue for mig-29, he can't.
how do you call this action of slewing the radar up/down and left/right? i cannto find the command in the control list :(
FYI: The Target Designator (U/D/L/R) sensor setting, in the keybind options area, is the same thing as the TDC Slew (Vert/Horiz) in axis commands. I asked that question on the forum and that is the response I got.
Its only 'heads down' if the pilot has more than one head. otherwise the term is 'head down'. or 'eyes down'.
letter A on top of Atk means he is bandit, Afr means friend
thx
he says "I don't know" and "I'm not sure", ALOT in his videos.... which isn't the best thing for a tutorial. Still glad to have watched
that's one hell of simulation software !!
Thank you man
The IFF and datalink is so much an advantage against the f18 right now that it makes the game really unfair/ not even mentioning the IRST and tws mode..
Nice video man thanks for your effort
thx
I came for the shooty shooty part
Nicely done!!!
The number at the bottom if i am remembering correctly is slew increment so when you move the dish it is moving 10 degrees you can change it to be more or less per move. I could be wrong been a while since i flew the flanker.
The number down the bottom is the predicted target range, the number on the right side represents the radar elevation in 1000m increments. The angle the radar antenna moves is directly related to the target range number; the larger the number, the smaller movement the antenna makes.

@@NeccronixExactly.
I want that Su 27 skin!
me 2 where can we get that ? looks like su 35 Camo
Scan Distance is what Key Stroke ? I cant find it ??
The lower right radar screen in your video shows an independent value for the "range" - I dont think I have seen that before ?
Also what keystroke slews the radar cone right and Left . I used to know but cannot find it anywhere using any type of search ?
I still dont get how is the mighty ability of Su-27 and similar ACs stealth no-radar IR attack is done with radar turned off? And is the auto-lock targets simplification bugged or in what conditions it should work? Been trying to figure the whole day how to out-range the F-15s in the nevada training mission. I get 1-2 of them at close range and then eject...
very useful,thanks
Sorry for the question but, the action you're trying to do from 13:25 (Slewing) how is it called in the controll of the game? as i cannot find it at all. not knowing the name i cannot set a key :(
I have two question
1 : is there any other radars than pulse Doppler radar
2 : can we notch other radars than pulse Doppler radar
the english cockpit for Su 27 plz

Have they updated so that the flanker can use datalink with other flankers?
Wait, if the true airspeed is shown in km/h, then why does my SU-33 max out at 1100 km/h?
Looking for players wanted to team up for REDFOR side to play together in organised way (jTAC/AWACS/Fighter Pilots/Strike/Helicopters on SRS/discord) on DDCS dynamic caucasus server.
I have a question about the IFF system in DCS.
How does it respond when interrogating something that (I assume) doesn't have an IFF transponder like a Spitfire?
Am I right in assuming that it would tell you the Spitfire was unidentified/enemy regardless of if it was on your team?
IFF is not modelled. Your interigator just "knows" if he is friend of foe. Maybe one day there will be proper modelling.
Ah, the possibilities for friendly fire would be endless!
Oh well, a man can dream.
Can you get bitching Betty in English instead of Russian? It’s kinda common sense what she’s saying, when you about to dive into the ground, but just wondering if there is an option for English.
Two years late, but your best bet would be mods.
Why can't I "see" drones like the Reaper in the BVR mode? Only can see and lock them in less than 10km.
Strange. Small RCS? All I can think of...
Curious about EO -- Since there's no radar lock on the target, if you fire a semi-active or passive missile, such as an R-27ER, will your target receive missile warning? Or can you even fire that missile with EO lock?
It will receive the warning, so you're generally better off using the ET, as you can lock on, and fire without the enemy noticing a thing.
If you try to launch R-27(E)R in EO lock, you will have to hold down the weapon-release button for longer, radar will turn automatically on, lock your EO target and thus he will receive warning.
+1 to Baron Nomis response, the R-27ER or other radar guided missiles will have to have a radar target to have launch authorization so they can't be launched with an EO lock. You could do an R-27ET launch with EO.
You guys have / going to do a vietnam era campaign? Would be so sick!
Roger that
Why. On EARTH. Is something as fundamentally powerful and important as full Data Link modeling /not/ even a PRIORITY for the DCS devs, let alone in the game already?
Data Link being fully modeled would change how every aspect of the sim goes. It would reward teamwork to a scale never seen before. How in the hell is this not a thing?
Also, with the Radar superimposed on the HUD, if you want to use the radar cursor...which do you set as SOI? The Radar, or the HUD? Or....does the Su-27 even /have/ a SOI function given it only has one cockpit display at all.
got FC3 yesterday and try to understand the radar. what angle in front of the plane is covered by radar? or: do you _need_ to tilt the radar like he does @6:34?! im needed to do this always manual to find enemy planes? so many stuff to know :/ guess im going back to the 25t :)
You can either pitch the plane up or move the radar up. I think it's about 10° scan range
im using the mig 29 and everything is in russian, while everything is in english for you
how?
th-cam.com/video/czUJQcaX9G0/w-d-xo.html
Is high PRF useful when a target is trying to Doppler notch? Low PRF gives greater unambiguous range but is less sensitive to low-velocity targets. Perhaps high PRF would be useful when a target is trying to blend in using notching since it's likely to still have a little closing velocity. High PRF should also produce more energy on target.
I think so, but again, I'm not sure which PRF is best for which situation.
Low PRF is best for long-range search and high PRF is best for shorter range tracking/targeting and cluttered environments.
I don't know the ins and outs but in general High PRF is better at detecting hot targets and Med/Low is better for flanking or cold targets. I would assume that if a target were trying to notch then switching off of High would help. I tend to use High almost exclusively, at least once I get a RWR alert, because I care more about hot targets than cold. That's probably a noob move but it seems to work most of the time.
What do you mean by "hot" and "cold" targets? What does that mean in a radar sense? Hot= closing in? Cold = moving away?
Pretty much. Hot basically describes when they are pointed at you and cold is when they are pointed away. You could also say that when your bearing to them is less than 180° they are hot and if your bearing to them is more than 180° they are cold. It doesn't really matter if you're pointed at them or not but rather how they are pointed to or away from you.

how to change the hud symbology from Russian alphabet to English?
Go to setting gameplay then i think its switch avioncs or something then switch it to english
can you not get the kind of map on the radar screen in mig29?
neg
How can I switch the hud from Russian to Englisch?
th-cam.com/video/czUJQcaX9G0/w-d-xo.html
Are the 27, 33, and MiG 29 all full sim?
Neg they are all low detailed models. $10 each.
how come you can look at thirdperson view with track ir when i do that it does not allow me to use track ir to look.
I’m still not sure, when I look at the radar, it’s a duplicate of the hud, how do I get the top down view?
Never mind I found out the mig 29 doesn’t have top down
where's all the grim reapers at? ive been looking for them since i started no servers or nothing *sad face*
5:01 How do you get that zoomed in on the HUD (or is that through editing?)? With my trackIR even if I put my face right next to the HUD the text/symbology stay the same size
Mouse scroll key or numpad * and / key
It's an actual zoom bind, unrelated to head tracking
how do u turn on the damn raDAR
\
press "i"
Why am I watching this video if I keep getting “that was in another video” or “you have to research that yourself”??effective waste of time
There’s so much info provided in all the videos, maybe you should figure your own shit out instead of complaining
This is a Su! Not an SU, goddammit!
Its Cyka
Why make a tutorial without knowing all there's to talk about?
You people flood TH-cam with your video game you should put in the title what your video entails you see I'm looking for real world radar footage of an sU 27 not your sim imaginary world and you see how aggravating this could be right
Yes we are on youtube, welcome to the channel :)
It is said in the title (dcs world)
Yeah, it actually says DCS World in the title though I can understand one may not be familiar with this name. Anyway, you're very unlikely to find real world footage of the radar on any aircraft in active service.
Lmao good luck getting real footage
