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.
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
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.
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
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.
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.

Awesome to hear! I wish you the best with your class.
Maybe the best video I've ever seen on youtube.

This is the best on this topic i have seen till date
You do such an amazing job, I’m going to watch and like all your videos.
This is a Corporation rolling academic app called Matrix laboratory
This is GREAT video to understand the chirp signal!
Sir, you made the subject easy with clear graphics and a great explanation just loved it.
Amazing explanation!

Great Video. I'll have to scan the achieves.
Thank you for the interesting content. I have a question please, what is the sampling rate to use in LFM to reconstruct the received signal ?
THIS IS AMAZING! Could you do a video on EMI/EMC in regards to RADAR Systems?
Superb animated explanation..
The best video I ve ever seen
Awesome! Glad you liked it.
Is it a NLFM or LFM signal you have mentioned sir ?
Amazing explanation. Thanks.
Can we use this app in smartphone ( analyser app )
You made a awesome video...thank you sir..

Wonderful!
Thanks!
Your teaching abilities are quite scary. Thanks.
Hahaha, thanks!
You taught a caveman programmer like me a ton. Thank you.
Superb!!
thank you very much
thank You!
Why are you showing a wave form of different phase during corelation...
What do you mean
Hmm convolutions
COMIC SAANS!
i any one want to learn matlab i will try to teach them for free
