| 摘 要： | 数字射频存储器(DRFM)通过对雷达信号进行复制和调制,能对雷达产生良好的干扰效果。基于加权网络分析了3bit相位量化DRFM干扰信号特性,提出利用等均值离散的方法求得加权网络的加权值,建立了3bit相位量化DRFM时域波形表达式,分析了3bit相位量化DRFM干扰信号的频谱特性。利用PD雷达模型对DRFM干扰效果进行了分析,仿真证明DRFM对PD雷达具有良好的干扰效果。

| Abstract: | The digital radio frequency memory（DRFM）can jam radar effectively by replicating and modulating radar signal.Based on weighting network,the character of 3-bit phase quantization DRFM jam-ming signal is discussed.The weighting value of weighting network by the method of equal mean disperse is proposed.The signal expression of time domain is constructed and the spectrum is analysed.The jamming effect on radar is studied by PD radar model and the simulation proves that DRFM technology is very effective for jamming PD radar. |
