Abstract

A method of handling radar signals of a radar system having a plurality of antennas is provided. The method may include generating a plurality of time-based radar signals based on a radar signal received by an associated antenna of the plurality of antennas, and transforming each time-based radar signal of the time-based radar signals into radar signals that each comprise a plurality of pairs of a frequency-based-value and an associated intensity value. The method includes storing the frequency-based-values and the intensity values of one frequency-based radar signal corresponding to one time-based radar signal of one antenna of the plurality of antennas; and storing each intensity value of the plurality of intensity values of another of the plurality of frequency-based radar signals based on a corresponding intensity value of the one frequency-based radar signal, wherein a stored representation of the intensity value of the other of the plurality of frequency-based radar signals has fewer bits than the corresponding stored intensity value.
