1. A method of handling radar signals of a radar system comprising a plurality of antennas, the method comprising:
processing a plurality of radar signals for determining a distance between the radar system and at least one target and a velocity of the at least one target, thereby forming a plurality of processed radar signals, wherein each radar signal of the plurality of radar signals is received by an associated antenna of the plurality of antennas;
digitally beamforming the plurality of processed radar signals for a plurality of beam directions, thereby forming a plurality of beamformed radar signals; and
summing the plurality of beamformed radar signals from the plurality of antennas according to beam direction, wherein the summing comprises coherently summing the plurality of beamformed radar signals from the plurality of antennas per beam direction.
