MMWCAS-DSP-EVM: Signal processing range pprofile thick green line

Dear engineers in TI,

For the signal processing script 'cascade_MIMO_signalProcessing.m' in matlab, what is the thick green line mean? And why is it the (Doppler FFT size)/2+1 column of sig_integrate?

Regards,

Garrett

    Hi Garrett,

    The thick green line, as mentioned in the title of the plot, indicates the Range profile of the zero doppler column. Zero doppler represents the stationary signature of the surrounding. Any static objects in the surrounding would have a peak in the zero doppler region. 

    If your doppler FFT ranges from -V bin to +V bin where 2V bins is the Doppler FFT Size, then 0V (zero doppler) would be indexed at [(Doppler FFT size)/2+1].
