为了有效评估高重频干扰对激光编解码的影响效果，采用归一化互相关函数法，量化分析了高重频干扰对精确频率码的干扰效果。以仅有干扰信号进入导引头波门、干扰信号超前制导信号一定时间进入导引头波门两种情况，重点分析了在激光解码识别过程中的干扰效果，仿真分析了不同因素对干扰效果的定量化影响。结果表明，不同重复频率的高重频激光干扰效果存在差异，重复频率为100kHz时干扰效果最好。该研究为增强高重频干扰效果提供了依据。

To estimate the impact of high repetition frequency jamming on laser decoding , the normalized cross-correlation function method was adopted .The effect of high repetition frequency jamming on precise frequency code during the distinguishing process of decoding was quantified under two circumstances .One was that only the jammed signal entered into the time-gate, the other was that the jammed signal entered into the time-gate at a certain time before the guiding signal.Experimental results show that the jamming effects are different for different jamming ferquency and the jamming effect is the best when the high frequency comes to 100kHz.The simulation of the effect of different factors provides the basis to analyze the jamming effect of high frequency signal .
