First the radar principle and the terminology is explained. Beamforming with a large number of array elements is the typical radar feature and the problems with such antennas are in other applications not known.
WebMIMO radar is widely used for automotive radar applications due to its ability to realize small angular resolutions in azimuth and elevation within a small package. For high-resolution 4D radar, beamwidths in azimuth and elevation less than 2 degrees are desired. Compute the number of array elements that would be needed to realize a 2 degree ...
