How can I plot a similar comparison plot in Matlab?

My attempt

I have tried to create a random function like/ Matlab:

rand(M, N)

and then take SFFT of it

fft(ifft(rand(M, N)))

and plot them using bar3 function in Matlab

enter image description here

  • $\begingroup$ You are just plotting random data. Why do you think that has anything to do with Doppler ? $\endgroup$

  • $\begingroup$ If your question is just about plotting, it should be asked over at stackoverflow. (Maybe you're looking for surf?) $\endgroup$

  • $\begingroup$ @Hilmar I want visual representation data in time-frequency and delay-doppler domain. Is it wrong what I did? $\endgroup$
