Hi all,
I am collecting data from AWR1642 using DCA1000 card to get raw data, and trying to use the configuration as in vital signs lab.
I am recording 200 data points per chirp, 2 chirps per frame and using only one chirp for further processing. my recorded data shape is : (n_samples,n_data_points,n_Rx) which is (n_frames,200,4).
my question is: when applying the FFT to data to get the range bin for each chirp, throught which axe I should do it ! which one is the slow time axis and fast time axis ! can anyone explain me in details !
thanks,
