Hi,I'm using the phased tool box to simulate a mmwave radar system by learning this example:https://ww2.mathworks.cn/help/phased/examples/radar-signal-simulation-and-processing-for-automated-driving.html
I was wondering how did they make the range-angle response plot? I used the RangeAngleResponse https://ww2.mathworks.cn/help/phased/ref/phased.rangeangleresponse-system-object.html and successfully plot the range-angle plot.
My question is how did they do that?What's the principle or algorithm of the RangeAngleResponse? If you know the algorithm,please let me know ,thank you very much!

It depends on the system. In summary, if you use an FMCW waveform, you want to use FFT to do range processing. If you use a pulsed waveform, then Matched Filter is a good choice. In terms of anglular response, it simply sweep the space with corresponding steering vectors.
