MATLAB: Ambiguity Function of FMCW waveform

ambiguity functionfmcwphased arrayPhased Array System Toolbox

I have seen matlab example of ambiguity function for LFM wave,so i was wondering if we can plot Ambiguity function for frequency modulated continous wave also?? can you give me example?

Best Answer

You could technically do it the same way, e.g.
hw = phased.FMCWWaveform('SweepBandwidth',1e7,'SampleRate',2e7,...
    'SweepDirection','Triangle','NumSweeps',2);
x = step(hw);
ambgfun(x,hw.SampleRate,1/(2*hw.SweepTime))
As a side note, there is also something called periodic ambiguity function which is designed for cw signals, but Phased Array System Toolbox currently doesn't offer that.
