This document refers to the out-of-box example. I would not reference it for the output format of the people counting code, which can be found here.

If you want to output the range profile for the zero doppler bin for the people counting project, you should reference and modify the code from the out-of-box project, or simply use the out-of-box project instead. I would also note that the people counting code may need some bigger changes to output the zero doppler bin of the range profile. Unmodified, the people counting code only computes the doppler FFT for the detected objects in the range/azimuth domain. You will need to modify it to compute a doppler FFT for all range/angle bins. See our demo implementation guide for more details.

Alternatively, since the zero-th element of an FFT is simply the sum of all the inputs, you could simply sum across all the range/angle elements over the chirp to compute just the 0th bin of the doppler FFT. This would not compute the entire doppler FFT though, it would simply return the zeroth element.

Best,
