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.

Abstract: According to an aspect, a tri-level digital to analog converter (DAC) comprises a first set of switches turned on to cause a first analog value with a first error as an output for a first digital value, a second set of switches turned on to cause a second analog value with a second error as the output for a second digital value, wherein, both the first set of switches and the second set of switches are turned on to cause a third analog value, proportional to the first error and the second error, as the output for a digital value equal to zero, and both the first set of switches and the second set of switches are turned off to cause a fourth analog value equal to zero as the output for a fourth digital value representing a reset state.
