Abstract
The dynamic range of the output of a radar system with a transmitter and receiver can be optimized by determining the phase of a radar reflection signal at the receiver and adjusting the phase so that the in-phase and quadrature components of the signal have equal amplitudes. The phase can be adjusted at the receiver or by adjusting the phase of the output signal at the transmitter.

A method of operating a radar system, the method comprising:
- receiving a reflected radar signal;
- generating an in-band signal corresponding to an in-band component of the reflected radar signal and a quadrature signal corresponding to a quadrature component of the reflected radar signal;
- determining a first phase amount corresponding to a phase shift required to cause an amplitude of the in-phase signal to equal an amplitude of the quadrature signal;
- phase-shifting the reflected radar signal by the first phase amount;
- and
- amplifying the in-band signal and the quadrature signal after phase-shifting the reflected radar signal by the first phase amount.
