Doppler compensation for binary phase-coded radar signals in presence of noise jamming

Abstract

Phase-coded radar signals and pulse compression offer the promise of exact range sidelobe cancellation. Using of these signals enables to decrease transmitted power of radar, to improve range resolution and resistance against various kinds of distortion or active jamming. The principal limitation of phase-coded radar signals is its sensitivity to the Doppler shift in case of moving targets. The techniques of the Doppler compensation in this case are effective. The Doppler compensation technique based on the Doppler Shift Emulator (DSE) with the multichannel correlation for binary phase-coded signals in presence of active noise jamming is presented in this paper.
