Slightly off topic, but this topic drifts from link to some digital antennas.I found - some old page with explanation of basics in really simple words:https://www.eetimes.com/radar-basics-part-3-beamforming-and-radar-digital-processing/There is explanation of digital beamforming - creating simultinuesly many send - receive - beams - just using FFT(FFT for space domain, not for time. In other words, for each sample in time domain, before there is a need to do FFT for beamforming. May be a lot of processing but not for up to date processors)Other parts of series are also interesting, but I cannot reach them.
