Why is a Chirp Signal used in Radar?

Gives an intuitive explanation of why the Chirp signal is a good compromise between an impulse waveform and a sinusoidal pulse waveform for radar.

this was the 4th video I have seen on this. Also was the only one that made some sense. THanks for posting this.

Good stuff! Thanks for such well explained intuitive content. Subscribed!!

very nice talk, one trick on RX to get chirp compression with low time sidelobes, is to time window the reference chirp signal before being placed in the rx matched filter. cheers

At first, thanks a lot for the nice tutorial. all make sense. 
worth to mention, that in practical chirped radar both s(t) and matched filer is realised in analog domain. which makes it really elegant solution.

Der professor,
Thank you for this wonderful explanation. You can make them practical to understand. Everything becomes clear when I watch your courses

[michaelbauers]

Thanks for this. Helps to understand that it's complicated.

sir It was one of the hard topics for me before I saw this video of yours you are a life saviour thanks sir 😊

[stringstoparadise]

thanks, sir for the video I have done my project using chirp as a basis function it has made my concepts clearer now

[noureddinetakoucht]

Thank you, Please can make a video explaining the signal form in each LTE stage transmitter. Thanks

[BeierJing]

Dear professor, thank you for the perfect explanation.But I have a question, when we use FFT to ensure the position of one object, for chirp from Rx?or for multipling chirp from TX and RX？

really fascinating concept enjoyed the video thanks for it !

[tuongnguyen]

Dear professor, can you make a video that explain what is "Rate-Splitting Multiple Access" ?

Dear Professor, thank you very much for the tutorial, this video has been a tremendous help for me when I was starting to learn about radar, this really has made it easier for me to learn all the follow-up material regarding radar.

I have one question if you don't mind me asking. I am currently operating a radar instrument, inside the module, a hardware for signal mixing to retrieve the delta function signal (dechirping) is already installed. In the manual, I read that signal mixing is done, in mathematical sense by multiplying the complex conjugate of the received signal and the transmitted one. I am curious about how and why the complex conjugate operation is performed to the received signal. I am aware that complex conjugate means the inversion of sign to the phase or the reversing of oscillation in real world sense. But I don't understand how it's actually happening to the received signal.

I would really appreciate if you can help me with an answer because I cannot seem to find one by searching myself and I don't really have any background on electrical or communication science. Thank you very much again for the wonderful tutorial.

I'm getting a little bit confused here, is the signal that you send similar to a barker code or is it a complete different thing ? I heard that barker code were designed to have a thin peak after autocorelation

Thanks, on the upper left image, isn't the period time a bit smaller?
It seems as if T marks the double period time.

amazing professor with an amazing concepts thanks lain!

Hi, all your videos are really interesting

[ariyakrishnan]

Sir can you do a video on range Doppler compensation algorithms?

[alicantasdemir]

Thank you prof. Ian, Can I have what you talk about in the video in writing?

[DeadCatX]

Excellent video. Very clear presentation. Is your accent from Australia?
