Pulse waveform basics: Visualizing radar performance with the ambiguity function

This tech talk covers how different pulse waveforms affect radar and sonar performance. See the difference between a rectangular pulse and a linear frequency modulated pulse, as well as how to use this comparison to build some intuition behind the ambiguity function. Along the way, learn how LFM waveforms improve resolution and signal-to-noise ratio through pulse compression.

just subscribed...when you encounter excellent teaching it is VERY obvious! this teaching stands head and shoulders above so many others on youtube...teaching is a skill and you certainly have it! very much looking forward to more of your content

[@samudralajagadeesh1246]

you saved at least 2 hours of searching, preparing notes from various sources. I am an undergraduate teacher, i visited many websites how to exactly teach a concept of "pulse compression in radar system". this video helped me a lot.

[@BrianBDouglas]

Awesome to hear! I wish you the best with your class.

[@user-bo1sq2vb4k]

Sir, you made the subject easy with clear graphics and a great explanation just loved it.

[@manjunathp1340]

This is the best on this topic i have seen till date

[@Teddy80s]

This is GREAT video to understand the chirp signal!

[@shubhamnayak9369]

Amazing explanation!

[@halilserdalsahin9764]

Maybe the best video I've ever seen on youtube.

[@Shhheye1]

You do such an amazing job, I’m going to watch and like all your videos.

[@TymexComputing]

This is a Corporation rolling academic app called Matrix laboratory

[@rishavchandel2751]

Amazing explanation. Thanks.

[@bouyeddaabdellatif8944]

Great explanation

[@yorkshire_tea_innit8097]

Great Video. I'll have to scan the achieves.

[@loremipsum3147]

Thanks for the amazing video. I have a question. Does it make sense to use 2 chirp signals added together to cancel the effect of doppler. First chirp linearly increases and second chirp linearly descreases. Doppler should apply as addition or subtraction to both so we can use combined chirp signal to cancel/calculate doppler? Like f1+ f2 = const.... (f1+doppler) +(f2+doppler) = measured..... doppler = (measured-const)/2

[@sin7wu]

THIS IS AMAZING! Could you do a video on EMI/EMC in regards to RADAR Systems?

[@stascho7579]

Love your videos!

[@akhileshmarar6414]

You made a awesome video...thank you sir..

[@user-ss4ny7sf9u]

thank You!

[@AmmarAhmedSiddiqui]

Superb animated explanation..

[@theoryandapplication7197]

thank you very much

[@Unknown-ki8yk]

Never seen such a clear explanation.

[@BrianBDouglas]

🥰

[@darinpeev5820]

Wonderful!

[@BrianBDouglas]

Thanks!

[@magicstix0r]

Fun fact: Bats do the same thing with their SONAR.
They have an FM sweeping chirp, which they use for matched filtering and high range resolution.
They also have a CW pulse for doppler resolution, but moths learned to stop flapping their wings when they hear it, so the bats also have to do FM sweeps.

[@BrianBDouglas]

🤯

[@sohaibnouicer5940]

Is it a NLFM or LFM signal you have mentioned sir ?

[@kakhaval]

Nice presentation but the principle of single tone versus chirp correlation is more general than just Radar application. A single tone correlation with its template gives triangular output while chirp gives high unmistakable peak. Example is Zadoff Chu sequences used in LTE delay measurement.

[@r.ksangwan1633]

Can we use this app in smartphone ( analyser app )

[@ebeb9156]

not to mention that CHIRP has lower PAPR compared to nearly anything. Which means you may use lower energy PowerAmplifier, which means cheaper radar, that dont overheat and remains reliable etc etc etc.... oh, and CHIRP has constant envelope which means that PowerAmplifier can be non-linear and use even lower energy.

[@jasonoconner7863]

You taught a caveman programmer like me a ton. Thank you.

[@phy6geniuxYTcreations]

Hmm convolutions

[@zedmike]

COMIC SAANS!

[@fawadfawad-xu9zs]

i any one want to learn matlab i will try to teach them for free
