摘要
文章分析了DRFM距离拖引干扰的工作原理,建立了干扰的信号模型。根据自动增益控制(AGC)变化对干扰进行了检测,在此基础上利用随机参差重频的方法对距离波门前拖进行抑制,在不同的干信比下分别进行了外场试验验证,通过对试验结果的分析表明了该方法能够有效的抑制干扰。
Operation principle of digital radio frequency memory(DRFM) range gate pull in (RGPI) jamming is an- alyzed and jamming signal model is constructed. Firstly, detect jamming through automatic gain control (AGC) transformation ;then carry out RGPI jamming suppression by using random pulse repetition frequency(PRF) meth- od;finally conduct filed tests with different jamming/signal ratios. Test results verified that this method can effec- tively suppress jamming sighals.
