为有效评估高重频对抗制导武器的效果,研究干扰频率、波门宽度、编码方式和干扰时机等因素对激光高重频干扰效果的影响,首先,通过深入分析导引头抗干扰关键技术和高重频干扰机理,建立了码型识别模型、波门设置模型和高重频干扰模型;而后,设计了弹道仿真流程,基于过重力补偿比例制导导弹弹道仿真平台,评估了不同影响因素对高重频干扰效果的影响。仿真结果表明：干扰频率和波门宽度对高重频干扰效果的影响较大,频率越高、波门宽度越大干扰效果越好;LFSR状态码对高重频干扰的抗干扰性能比二间隔码好;且在干扰频率达到100 k Hz时,高重频对波门宽度为20μs的二变间隔码的干扰效率能达到100%,脱靶量达到510.4 m;而干扰时机对干扰效果影响较小。文中的研究成果可为高重频干扰装备研制和战术使用提供一定的参考和依据。

英文摘要：

To evaluate the jamming effect effectively, the research on the jamming influence of the laser high repetition which is made by interference factors of interfering frequency, wave door width, encoded mode and jamming moment was carried out. Firstly, three models of wave gate setting, coding identification and high repetition jamming were set up through deeply analyzing the anti-interference key technology and jamming mechanism. Secondly, a scheme was put forward, which was about judging the jamming signal in time gate and simulating the trajectory by the judge. Finally, based on the proportional guidance with over gravity compensation trajectory simulation platform, the effects of different factors on the high frequency jamming were evaluated. The result shows that interference frequency and wave gate width have a greater influence on the jamming effect, and the higher the frequency and the wider the wave gate are, the better the jamming effect is; the anti-interference performance of long cycle code is better than short cycle code; when the interference frequency reaches 100 k Hz and wave door width reaches 20 μs, two space code can be completely jammed and miss distance can reach 510.4 m; jamming moment has a smaller effect on jamming effect. The results may provide some reference and basis for the development and application of high repetition jamming equipment.
