- Radar is pretty ubiquitous nowadays, but how does it really work? There's a lot more to it than you think and this series is here to explain it. In this video we'll go over the basics of radar waves. It'll teach you everything you need to understand more advanced topics like finding range, speed, and low RCS targets.
In future videos we'll also delve into the shadowy world of EW. That's Electronic or Electromagnetic Warfare depending on you ask. But either way it concerns the same thing. I don't see a lot of discussion on it, mostly because it's confusing and some areas are off limits to the public. But there's a vast swathe that can be talked about in public and that's what we'll cover.
So I hope you'll join me on this journey which all starts with Radar 101.
For further learning on radar I recommend watching this lecture series:

It was a clear and nice explanation. Please do not stop/limit this series to mechanical pulse doppler radars. I would love to see a pesa/aesa series and if possible more advanced engineering focussed videos too if possible !
Scanned arrays are on the list.
And also SAR would be great
what man ? U guys used red to stop jobs for faculty who had primary mail account with gmail ....
Somebody opened gmail and .....to differentiate her mail from mine they guys used red and put an end of my job ........
Red for stop and local guys used blue lights for vehicles
Thank you. An excellent guide for beginners.
Mike. I absolutely love this content. I tried going through an old video by Whitehorse via TH-cam for basics of High, medium and low PRF lessons. They were methodological and patience in their presentation. I might have walked away with a mere 30 to 40% of their lesson plan. I have also gone through several more articles (some from the Navy graduate level lecture notes/PowerPoints, some from other articles explaining PRF and RADAR basics). Your video here is the greatest so far. I look forward to it, and sincerely hope you will develop this RADAR education series further. So many thanks to this. Thank you!
This is by far one of the most informative videos I have seen to date on radar operation. Great job!
A+ as always. Very keen to see this progress.
Thanks again!
Super useful video, looking forward to the next ones in the series. Thanks a lot for doing this!
Very well made video mate, from playing DCS for about 2 years now I knew how radars worked in practice but it is very interesting to know about the science behind it
This is a masterclass in how to use TH-cam to introduce a complex subject. Superb content!
You deserve more followers. Your channel is truly a reference for DCS. Keep up the good work!
A very interesting start and I look forward to seeing what direction you take with this.
Another great video. Thank you for this high quality content.
You're an asset to the community.
standing o again. your channel has become my go-to for information on the elements in dcs which I only slimly understand. hoping you get to reap the benefits of your work with increased subscriptions.
Looking forward to the rest of this series!
Man what a great video. I started playing DCS short time ago and as any enginerd out there I started looking for sources to study the different systems. Radar was the first and wow your videos are excelent!! Watching part 3 right now, can't wait for more. Do you have books to suggest? or other sources? Do you plane to release more videos on the topic? 10/10 content, cheers!!!
love how you handled this topic, very insightful!
ugh... that was one of the best videos on radar intro i have seen in a while....
Very good video, looking forward to next in the series.
Best and the most detailed explanation i have ever seen
Thank you for this video
I wish everyone online would be as good as you explaining any topic :)
What an excellent video! A clear and easy to follow presentation. I have learned so much. Thank you.
GOLD! Simple & brilliant. Thank You.
Great work, Mike! Thank You!!!
I can't wait for more!
Excellent explanation, loved it!
This looks like an awesome series! Can't wait for more :)
You mentioned that PRF is going to be discussed is future videos - would you be able to touch on how the uncertainty principle affects those ranging calculations? I remember that this is primarily what dictates the use of MPRF vs HPRF but don't remember the exact explanation. Thanks for your videos, these are fantastic resources!
Pulse radars will be the topic of the next video. Explaining ambiguity in a comment won't really do it justice. It will be explained in detail in that video.
Doppler (aka frequency shifts) will be the third one. To really understand when to use MPRF vs HPRF you will want to see that video too. There's a tradeoff between the two. I want to make sure that's clearly detailed for everyone, because I haven't seen it really spelled out in other sources.
Look forward to more on this series
This is so great. I wish I had this video series in USAF intel school.
This is brilliant content, simply brilliant.
Great video! It shows that by the level
of simulators we have today they can be used as educational tools as well.
Thank so much for the video. Thumbs up. 🙂
loved it😮,,, what a clear view of RADAR
Thank you for this video. I really enjoyed it 👍
Every sentence of this video spits out important information
Very good and philanthropist discussion.i would try to learn this topics by thinking and writing.
Amazing explanation!
Very good explanation.
Great video ! 👍
Thank you. You explained your subject matter so well.
Thanks, I appreciate the positive feedback.
Many thanks!
The teaching is awesome sir, could you please guide in FMCW radars
Thanks a lot ! What an explanation of how it works ! I still have a question : is there any modern radars that uses the ionosphere effect to spot on target that are behind the earth roundary surface ?
I've never heard of one using the ionosphere that way (though I do know low frequency radio operators like to use that trick to transmit farther). There are radar systems that use ground waves and the slight bending caused by gravity to get returns just beyond the horizon. So the LOS radar horizon isn't exactly the end of the line for radar. It can go a few miles past that point.
Excellent video sir! 👍🏼 Great work + visuals. 📡✈️
Btw - do you have a website or contact info?
Perfect.
You the best ❤❤❤
I would love to see a deetailed video explaining all the radar switches / functions for the upcoming F-4E module
I'd like to do something like this. However, first I would need to learn the system well enough to feel comfortable explaining it.
Right now I'm doing that for the F-16. So there will be a video explaining the Viper's radar functionality. But maybe afterwards (once I've had some time to get to know the F-4) I can do one for the Phantom too.
Ohhhh boyy!
That'd be great for my book and orbital defense.
chocolate bars in my pocket melt without a classified military radar sitting next to me 😂
Great video man 🤟
11:12 Why would the upper left one which is farther away, distance wise appear as a ghost detection?
But is the frequency of the wave received back by the receiver (after it reflected from the object) is it the same frequency as the wave sent by the antenna etc? ..thats what I want to know...also does the same principle apply to sound waves? Like can there be a sound based radar?...thanks
The frequency of the radar echo can change. I encourage you to watch the rest of this series where we go into more detail about this phenomenon.
As far as sound wave based radar, that's called sonar and it's used to find submarines. Sound waves propagate much faster underwater than in the air so its ideal for use there.
❤
i saw your ppl get close a few times....
but those crooks follow me everywhere....
even cut in front of every checkout line that i go to stand in
this is why your rwr gets pinged when flying close to other aircraft 11:45
Discovered in 1940s? Seems like this is false as this is part of classical physics and was known since 19th century or earlier. 1940s is probably when it was first used practically, not when it was discovered that both radio waves and micro waves are a form of electromagnetic radiation.
Radar was discovered in 1940s just it's not like current era Radar. It was a search radar and wasn't like current radar but some World War 2 planes had radar and they used it to find aircraft and that's all it could do just search for aircraft hope it helped
Is there anything Radar doesn't pick up?
If you're talking about radar reflectivity then everything short of a black hole should reflect some energy to a degree. Even stealth aircraft reflect some energy back.
Remember, that your eyes are a form of EM receiver. They are just tuned to a very small band of frequencies that make up the light we see. But they are EM waves just like what a radar sends out and receives. So if something reflects light it will reflect radar too. Even matte black paint reflects light. Just not as well as a mirror.
The key here is how the radar system processes these reflections. A lot of systems filter out ambient EM noise and things they perceive as clutter. So the threshold for hiding a contact in that filtering varies from one system to the next.
In a future video I'll cover more on how radars handle this stuff. It should explain how aircraft disappear into the background noise (which is how stealth aircraft evade radar).
Most people don’t get involved in military planning, so they tend to have blind faith in the competence of our military leaders.
Sadly, that faith is misplaced. Our Joint Chiefs of Staff didn’t get hired for being smart. They got hired for being cunning. For them, the issue is always “Money”. How can the Army get more?
In my view, all of those men should be replaced. But then you’re faced with the difficult task of choosing replacements.
The military claims that Officers shouldn’t be recruited from the civilian economy, because they don’t have enough experience. I think the less experience they have working with crooks, the better.
So if civilian Chiefs of Staff are brought-in as replacements, then what qualities should they have? I can think of a few. The first is an understanding that war is for killing. The objective is to achieve the highest mortality rate possible of non-American military and civilian personnel. If a guy can’t agree with that, he’s not Officer material.
The second qualification is the ability to think on the fly. In a war, things change every ten minutes. Old men aren’t able to deal with chaotic situations. So I would limit the maximum age to thirty five.
And then I would try to choose men who have an easy Cowboy sense of commitment. A Cowboy doesn’t wear his heart on his sleeve, because he doesn’t have to. He’s already decided on the outcomes.
I dont understsnd😅
Radar is the work of Nikola Tesla. Nikola Tesla made a sketch of a radar that was published in the Electrical Experimenter in May 1917. Do not attribute Tesla's works to others. Please
He's dead, I don't think he'll mind.
Okay Joe Rogan
Flat earther hate this video.
Quite the opposite . The explanations in the video prove that radars only work with long ranges on land Flat.
Apart from bouncing them off the ionosphere for over the horizon radar
