随机重频激光制导雷达抗高重频干扰技术OA北大核心CSTPCD
Laser guidance radar anti-high-repetition-frequency jamming technology based on random repetition-frequency signal
为了能有效对抗高重频干扰,在分析高重频干扰破坏激光制导雷达信号处理机理的基础上,采用了随机重频照射激光波形,并利用激光目标指示器、目标和探测器的先验距离、速度特征,提出了基于自适应交叠波门的高重频干扰信号排查和鉴别方法,有效控制了重频干扰对目标捕获环节的影响,形成一套从波形设计到信号处理、目标捕获的端到端的抗高重频干扰解决方案,并进行了理论分析和实验验证.结果表明,在不同干扰场景下,有效捕获目标的时间均低于0.2 s,捕获时间在亚秒量级,与无干扰…查看全部>>
In order to effectively counteract high-repetition-frequency jamming,a solution based on the analysis of the destructive mechanism of high-repetition-frequency jamming on laser guided radar signal processing was developed.The solution involves the use of randomly modulated laser waveforms and incorporates prior knowledge of the distance and velocity characteristics of the laser target indicator,target,and detector.A high-repetition-frequency jamming signal i…查看全部>>
