Questions in FMCWExample about plotresponse

i want to get the value of the plotresponse,how can i do?

i want to get the max value in this Range-Speed picture.

I assume that the example is the "Automotive Adaptive Cruise Control Using FMCW Technology" example and the plot comes from the phased.RangeDopplerResponse class.

To get the max value of the Range-Speed picture, I suggest capturing the step output of rngdopresp.

% Determine maximum value

resp = rngdopresp(xr);

respPower = abs(resp).^2;

respPower_dB = pow2db(respPower);

maxRespPower_dB = max(respPower_dB(:))
