摘　　要：针对传统噪声在干扰LFM脉冲压缩雷达时干扰功率利用率不高的问题，提出一种灵巧噪声干扰实现方法。该方法将DRFM存储的雷达发射信号与噪声信号相卷积得到灵巧噪声信号，这种信号干扰能量利用率高，能产生压制性和欺骗性双重干扰效果。文章从理论分析和仿真实验角度证明了它能有效干扰LFM脉冲压缩雷达，且性能明显优于射频噪声干扰。Aimed at the problem that traditional noise jamming has the low utility of jamming power to LFM pulse compression radar, a smart noise jamming realization method is proposed in this paper. With this method, the radar signal stored by DRFM and noise signal are convolved to get the smart noise. This kind of jamming signal not only can have the high utility of jamming power, but also can produce blanketing and deception jamming effects. It is proved to be more effective than RF noise jamming for LFM pulse compression radar by theoretical analysis and simulation.
