摘　　要：对抗激光半主动制导导弹,高重频激光干扰是一种有效手段。为分析高重频激光对采取不同脉冲录取技术的导弹的干扰效能,建立了高重频激光干扰效能模型。分别对导引头波门首次干扰成功的概率、第二次干扰成功的概率以及将目标指示信号诱偏出波门所需干扰次数进行了仿真模拟,研究了高重频激光重复频率、波门宽度等因素对干扰效能的影响。仿真结果表明,对采取首(末)脉冲录取技术的导弹,干扰重复频率越高,波门宽度越宽,干扰成功的概率越高,将目标指示信号诱偏出波门所需的次数越少。对采取最优时序脉冲录取技术的导弹,首次干扰时,干扰重复频率越高,波门宽度越宽,干扰成功的概率越高;在首次干扰成功的条件下,第二次干扰成功的概率随干扰激光重复频率的增长而趋于平缓;并且将目标指示信号诱偏出波门所需的最佳干扰频率位于波门宽度倒数附近。研究成果可为装备研制及作战运用提供参考。To countermeasure semi-active laser guided missiles,high-repetition-rate laser interference is an effective means.In order to analyze the interference efficiency of high-repetition-rate laser to missiles adopting different pulse admission techniques,a model describing high-repetition-rate laser interference efficiency is established.The success probability of the first interference of the seeker’s wave gates,the success probability of the second interference,and the interference times required to deflect the target indication signals out of the wave gates are simulated,and the effects of high-repetition-rate laser frequency,wave gates’ width and other factors on the interference efficiency are studied.The simulation results show that as for missiles that adopt the first(last) pulse admission technique,the higher the interference frequency and the wider the wave gates’ width,the higher the success probability of interference,the fewer times required to deflect the target indication signals out of the wave gates.When the missile adopts the optimal timing pulse admission technique,in the first interference,the higher the interference frequency and the wider the wave gates’ width,the higher the success probability of interference.Under the condition of successful first interference,the success probability of the second interference tends to level off with the increase of the frequency of interference laser.The optimal jamming frequency required to deflect the target indication signals out of the wave gates is located near the reciprocal of the wave gates’ width.The research results of this paper can provide reference for equipment development and operational application.
