Abstract
Methods and systems that reduce the effect of phase noise in radar receivers. The received phase noise spectrum is modulated with periodic nulls due to the two way range delay function. The system and method include strategically positioning the nulls of the delay function to cancel portions of phase noise power spectral density, the portions of the power spectral density of the phase noise being selected so that effect of phase noise in radar sensitivity is reduced.
