Time Delay and Doppler Shift Estimation Accuracy Analyses of Moving Targets in Non-cooperative Bistatic Pulse Radar

摘要：

According to the characteristics of non-cooperative bistatic pulse radar systems and the issue that the doppler mismatched loss of the cross-correlation detection of moving targets is serious, two fast methods for joint time delay and doppler shift estimation of moving targets, based on segment correlation–FFT processing and modified partial segment correlation–FFT processing, are proposed, after analyzing the common methods for cross-ambiguity function processing such as direct calculation, FFT, Zoom–FFT method. The processing performance of direct calculation and partial segment correlation–FFT processing of LFM pulse-series is analyzed in theory and by simulation. And the simulation shows that the weak moving target can be detected effectively and the time delay and doppler shift can be fast estimated by the methods presented in this paper.
