1. A method for compression of radar signals received by a plurality of receive channels in a radar system, the method comprising:
generating, by the plurality of receive channels, a digitized intermediate frequency (IF) signal at each receive channel based on the radar signals received by the plurality of receive channels;
receiving, by a signal processor coupled to the plurality of receive channels, the digitized IF signals, wherein the signal processor is configured to process the IF signals to generate complex range values for each receive channel;
generating a compression parameter;
receiving blocks of the complex range values for each receive channel;
determining a compression scale factor for each of at least two types of compression and selecting from the at least two types of compression a selected type of compression based on the determined compression scale factors;
compressing, by an encoder using the selected type of compression, each block of the complex range values to generate a corresponding compressed block of range values based on the compression parameter; and
storing the compressed block of range values in a radar data memory.
