针对高重频激光干扰与不同激光编码之间关系的研究不够深入这一问题，采用归一化互相关函数法，量化分析了高重频激光干扰在搜索识别阶段对不同编码体制的干扰效果。仿真结果表明，高重频激光对不同编码体制的干扰效果存在差异；重复频率高于120kHz时，对所有编码体制的干扰概率几乎均为100％，各编码体制间无明显差别。
針對高重頻激光榦擾與不同激光編碼之間關繫的研究不夠深入這一問題，採用歸一化互相關函數法，量化分析瞭高重頻激光榦擾在搜索識彆階段對不同編碼體製的榦擾效果。倣真結果錶明，高重頻激光對不同編碼體製的榦擾效果存在差異；重複頻率高于120kHz時，對所有編碼體製的榦擾概率幾乎均為100％，各編碼體製間無明顯差彆。

Focusing on the fact that the study of high-repetition-frequency laser jamming to different coding systems is little,the normalized cross-correlation function is adopted to quantify the effect of high-repetition-frequency laser jam-ming on different coding systems in classification process. Simulation results indicate that the effect of high-repetition-frequency laser jamming to different coding systems exists differences;When the laser frequency exceeds 120kHz,the efficiencies of the jamming to different coding systems are almost 100%and there is no significant difference between the coding systems.
