摘　　要：弹目交会过程中的“早晚到”脱靶方位对引战配合效率有重要影响,利用引信探测目标回波多普勒频率结合导引头提高的弹目相对速度信息可以识别“早晚到”脱靶方位,并修正引战配合延时规律,从而提高引战配合效率。首先分析了“早晚到”脱靶方位对引战配合效率的影响,然后论述了利用引信多普勒频率结合弹目相对速度信息识别“早晚到”的可行性,最后给出了修正引战配合延时规律的方法和数字仿真结果。In the course of missile target intersection, the early or late of miss azimuth has important affection on the efficiency of fuze warhead matching. It can be easy to identify the early or late of miss azimuth by the information of missile target relative velocity which is enhanced by doppler frequency of fuze detection target backward wave in combination with seeker, and modify the delay rule to fuze warhead matching, then enhance the efficiency of fuze warhead matching. In this article, it firstly analyzes the infection of the early or late of miss azimuth on efficiency of fuze warhead matching, then discusses the probability of identifying the early or late miss azimuth by using the doppler frequency of fuze in combination with the information of missile target relative velocity. At last, it gives the method of modifying the delay rule of fuze warhead matching and the result of digital simulation.
