According to an aspect, a method of data compression in a radar system comprising, converting a plurality of ranges in a first data form into a polar form, determining a plurality of logarithmic values of the plurality of ranges in the polar form, quantising the plurality of logarithmic values of the plurality of ranges with a first bit width that is fewer than a second bit width in the first data form. According to another aspect, the method further comprising quantizing the logarithmic magnitude part with a third bit width and quantising the logarithmic phase part with a fourth bit width.
