Enhance the Efficiency of Fuze Warhead Matching by Doppler Frequency of Fuze

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.
