In /mmwave_sdk_03_06_00_00-LTS/packages/ti/datapath/dpc/dpu/aoaproc/docs/doxygen/html/index.html, it says:
"In addition to AoA estimation, this DPU also generates data for computing azimuth heat-map (e.g for visualization purposes), this data is 2D FFT of the phase compensated Doppler bin 0 (static objects) output of each of the range bins. The following figure depicts data generation for azimuth heat-map visualization."
Question 1: From upper description and figure, it looks like 2D FFT is done to all the range bins. Isn't the same "2D FFT" process had been done in Doppler DPU already?
Question 2: In "Azimuth heatmap preparation" section (as in below figure), "Static Clutter Removal" could be optionally enabled. But since Azimuth heatmap only consider Doppler bin 0 (static objects), if "Static Clutter Removal" is enabled, would the result heatmap become empty (no objects)?
Thank you.
