Abstract
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.

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.
A radar system comprising:
- an analog to digital convertor (ADC) generating a plurality of samples of a radar signal;
- a range generator generating a plurality of ranges from the plurality of samples;
- a polar convertor operative to convert the plurality of ranges into corresponding plurality of polar values;
- a logarithmic (Log) convertor operative to convert the plurality of polar values to plurality of Log values;
- and
- a memory storing the plurality of Log values;
