Hello. I am working on SAR imaging. I could not find any MATLAB functions to do range compression with matched filter when FMCW signal is used. After I recieve each reflected signal, I dechirp the signals. then I should implement range compression and then azimuth compression. can any one help me to do range compression in matlab?

Range compression is basically already implemented in the dechirping process. By applying the FFT to the filtered product of your tx signal with the rx signal you already get your spectrum which gives you the "compressed" range data.

thanks for your response. what do you mean by 'filtered product of your tx signal with the rx signal'. i.e. what should I do?
