Hi
I have a question about these virtual antennas. In capon beamforming and 2d fft processing, we always need two groups of rx antennas.
For example, we have 3 tx and 4 rx, 54 chirps for each tx, so we could get 162 * 4 data
But in some open sorce code, why do they transform data to 81 * 8 to process instead of 54 * 8, for what concerning.
example codes:
radar_cube = np.concatenate((radar_cube[0::2, ...], radar_cube[1::2, ...]), axis=1)
transfromed (164,4) to (81,8)
regards
