ABSTRACT:
A modulation is applied to a received radar signal prior to analog-to-digital (A/D) conversion, and is removed subsequent to A/D conversion, to mitigate the effects of nonlinear receiver harmonic distortions and receiver spurious responses. The received target and clutter signals pass unchanged through the receiver to the digital signal processing. Harmonic distortion products and spurious responses introduced in the receiver after the modulation has been applied are distorted by the demodulation signal. By proper selection of the modulation waveform, coherent harmonic distortion products and spurious responses are converted to wideband noise reducing the level of interference that competes with targets in the affected Doppler filters.
