摘要
通过分析激光半主动制导武器系统导引头波门设置和高重频激光有源欺骗式干扰的特点,提出在波门外判断取样、在波门内对比排除的抗高重频激光干扰的方案,讨论了关键点,包括高重频干扰的判定、参照信号的获取和干扰信号的剔除,并给出了Simulink仿真验证,结果显示波门内干扰信号能有效被排除而制导信号不受影响,表明所提出的方案在原理上是可行的。
Through analyzing the characteristics of wave gate setting and high-frequency laser active deception jamming of the seeker of laser semi-active guidance weapon, a scheme of counter high-frequency laser jamming is proposed by way of judging and sampling out of wave gate and comparing and eliminating in wave gate. The key points, which include judging the jamming, extracting the contrast signal and eliminating the interference, are discussed. The simulation experiment based on Simulink shows that the interference signals in wave gate can be eliminated effectively but does nothing to the guide signals, which indicates that the scheme is feasible in principle.
