Tool/software: TI-RTOS
Hi,
Referring to the document in /ti/mmwave_sdk_02_01_00_04/packages/ti/demo/xwr14xx/mmw/docs/doxygen/html/index.html, in 1D FFT (below) I have a few questions regarding the processing flow:
1) For the generation of a range-doppler plot, could I confirm that the post-FFT radarCube is more of a 256 by 192 data matrix as opposed to a 3D data cube since the diagram shows that the range information from the chirps occupy adjacent rows?
2) Are the received signals from each of the receive antennas appended in a 256 x 48 x 4 data cube instead?
3) Regarding the 2D FFT for doppler data, does a doppler FFT along the rows of the data matrix work if it occupies a 256 by 192 data matrix as opposed to a 256 by 48 by 4 data cube?
4) For the generation of the range-doppler log matrix, why is the magnitude of each element summed after the log-manitude step rather than the other way around? Does summing after log-magnitude not result in multiplication rather than linear addition?
