I collected Iridium (satcom) I/Q samples (5120 x 100000 complex double) and I would like to plot the range-Doppler response map by using the matlab tool
scope = phased.RangeDopplerScope( ... 'IQDataInput',true,'RangeMethod','Matched filter', ... 'Name','Range-Doppler Scope', ... 'Position',[560 375 560 420],'ResponseUnits','db', ... 'RangeUnits','m','DopplerFFTLength',1024, ... 'DopplerOutput','Speed','OperatingFrequency',fc, ... 'SampleRate',fs,'PropagationSpeed',c);
scope(( my 5120 x 100000 complex double),mfcoeffs);
How can I get my mfcoeffs? I found another Matlab tool ('getMatchedFilter' that uses a phase-coded waveform ) to get my mfcoeffs.
But it is recommended to use another waveform instead of a phase-coded waveform when you need to detect or track high-speed targets or Phase-coded waveforms tend to perform poorly when signals have Doppler shifts. it is my case.
So How can I get mfcoeffs?
