为测量高速导弹攻击靶船的脱靶量,提出在靶船上接收处理导弹发射调频信号,处理多普勒频率和相位,获得导弹相对于靶船脱靶量的测量方法。调频信号接收,采用最大似然估值技术的接收机,在正交开环的近似最大似然估值器中完成多普勒频率、相位估值。通过仿真分析表明:脱靶量测量精度小于1m,满足使用要求。同时脱靶量测量点固定,接收信噪比高,易于信号处理,使接收机结构简单,方便应用。

In order to score the miss distance of high speed missile attacking seaborne target,a scoring method is pre-sented for the position of missile relative to seaborne target, receiving FM signal of the missile for processing Doppler frequency and phase. The FM signal is received by receiver with maximum likelihood estimation technology. Doppler frequency and phase is carried out in approximately maximum likelihood manner of quasi-open loop. Trajectory simula-tion results shows that the precision of measuring miss distance undulates in 1m and the applying request is satisfied. Simultaneity, measuring ponit is not change for scoring, high receiving SNR is prone to processing, simply receiver, easy to application.
