摘　　要：脉间随机捷变频引信采取宽频带快速频率跳变,使得干扰机难以追踪和复制引信信号,解决无线电引信在基于数字储频的欺骗式干扰环境下的目标探测问题,同时减小压制式干扰对引信的影响。本文介绍了脉间随机捷变频引信的工作原理和组成,对脉间随机捷变频引信的抗干扰性能进行了仿真分析,对脉间随机捷变频带来的目标检测影响进行了分析优化。仿真结果表明,脉间随机捷变频引信具有良好的抗干扰性能。The broadband agile frequency technology is used in pulse-to-pulse random frequency agility pulse Doppler fuze to make tracking or copying fuze signal with difficulty for jammer.It can resolve target detection problem of radio fuze that is in the environment of deceptive jamming based on DRFM,and can reduce the influence of suppression jamming to fuze.This paper introduces the working principle and the composition of the pulse-to-pulse random frequency agility pulse Doppler fuze,then makes the simulation analysis for anti-jamming performance of the fuze,and analyzes and optimizes the effect of pulse-to-pulse random frequency agility on target detection.The simulation results show that the fuze based on pulse-to-pulse random frequency agility technology has good anti-jamming performance.
