中文摘要：
根据脉冲制非合作双基地雷达系统的特点,讨论了固定目标的互相关检测与时延估计原理,针对运动目标多普勒频移对互相关检测造成的失配损失很大而无法继续使用的问题,提出了一种＂分段相关-视频积累＂快速时延估计算法,并对线性调频脉冲串信号在互相关和＂分段相关-视频积累＂两种方法下的处理性能进行了理论分析和仿真比较。实验表明＂分段相关-视频积累＂方法能够在参考通道与目标通道的信噪比相差十分悬殊的情况下,有效地完成微弱动目标的检测与快速时延估计。
英文摘要：
According to the characteristics of non-cooperative bistatic pulse radar systems, A fast method for time delay estimation of moving targets, based on segment correlation-video integration, is proposed to solve the problem that the doppler mismatched loss of the cross-correlation detection of moving targets is serious. The processing performance of cross-correlation and segment correlation-video integration of LFM pulse-series is calculated and analyzed by simulation. It is demonstrated that the weak moving target can be detected and the time delay can be fast estimated by means of the segment correlation-video integration method, when the difference of the signal-noise ratio of the reference channel and target channel is very great.
