摘　　要：超前同步干扰以固定的超前量转发干扰信号进入激光导引头波门,干扰成功概率是基本固定的,并且干扰和制导信号同时在波门内,导引头有机会和条件采取进一步的抗干扰措施,根据实时波门的原理,提出一种基于波门诱偏的激光导引头干扰方法,设计了干扰信号,探讨干扰的机理,通过分析制导信号、干扰信号以及波门的时序关系和相互作用过程,得到了干扰条件下波门内信号分布,选择典型参数,仿真模拟了超前同步和波门诱偏两种干扰状态,得到了干扰条件下波门对信号录取的特性,概率分析验证了波门诱偏干扰的相对优势,分析结果可为干扰参数和过程的设计提供参考。The overshoot synchronized jamming forwards the jamming signal into the laser guide head wave gate with a fixed amount of overshoot,the jamming success probability is basically fixed,and the jamming and guidance signals are in the wave gate at the same time,so that the guide head has the opportunity and conditions to take further anti-jamming measures.According the principle of real-time wave gate,a new jamming strategy based on wave gate decoy is put forward in this paper.Firstly,the jamming signal is designed to explore the mechanism of interference.Then,by analyzing the timing relationship and interaction process of the guidance signal,the interference signal and the wave gate,the signal distribution within the wave gate under the interference condition is obtained.Finally,typical parameters are selected,and two interference states,the synchronization jamming and the wave gate decoy,are simulated to obtain the characteristics of wave gate on signal admission under interference conditions.The relative advantage of wave gate-induced bias interference is verified with probability analysis,and the analysis results can provide a reference for the design of interference parameters and processes.
