为有效评估制导雷达抗干扰性能,针对制导雷达技术特点及其面临的干扰环境,提出一种射频信号注入系统设计方案。该系统通过模拟器构建了包括杂波、干扰以及目标回波在内的复杂电磁环境,并将信号以射频注入的方式注入雷达数据处理回路,构建了逼真的战场环境。测试结果表明,该系统能够有效模拟目标/欺骗干扰、无源干扰和有源压制性干扰等复杂信号,且信号产生灵活、可控,为雷达抗干扰性能内场评估实验提供了逼真的电磁干扰环境。

In order to evaluate guidance radar's anti-jamming performance effectively, a guidance radar RF signal injection system was proposed.The system uses simulator to structure complex electronic jamming environment including clutter, jamming and target echo.Then the system injects the signal into the radar in the form of RF.The test results shows that this guidance radar RF signal injection system can simulate target echo, deception jamming, clutter and barrage jamming, and it can produce signal flexibly.It has great value which matches design requirement well, and satisfies assessment.
