Claim 5:
6. A radar system comprising:
a transmitting antenna transmitting a radar signal comprising a plurality of chirps, wherein the radar signal is a radio frequency (RF) signal;
a plurality of receiving antenna receiving a reflected signal, the reflected signal is reflection of the radar signal by one or more objects;
a plurality of mixers mixing a reference signal and a corresponding one of signal from the plurality of receiving antennas to generating a plurality of intermediate frequency (IF) signals;
a plurality of analog to digital convertor (ADC) sampling the plurality of IF signals to to generate a plurality of digital samples of the plurality of IF signals;
a range generator configured to generate a plurality of ranges from the plurality of samples of a reflected radio frequency (RF) signal wherein number of ranges T in the plurality of ranges being equal to P X N X M, in that, P representing the number ranges for every chirp, N representing number of chirps in the plurality of chirps and M representing number of receiving antennas in the plurality of receiving antennas;
a polar convertor converting every range in the plurality of ranges from the first data form into polar form to generate a corresponding plurality of polar ranges in polar form;
a logarithmic (Log) convertor converting every polar range in the plurality of polar ranges to logarithmic value to generate a plurality of logarithmic ranges; and
a quantiser quantizing every logarithmic range in the plurality of logarithmic ranges with a second bit width that is fewer than the first bit width to form a plurality of compressed ranges
wherein number of the plurality of polar ranges, number of the plurality of logarithmic ranges and number of plurality of compressed ranges are equal to the number ranges T in the plurality of ranges.
