摘要
利用数字射频存储器(DRFM)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。对基于加权网络的3bit相位量化DRFM干扰信号特性进行了分析,提出了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,探讨了3bit相位量化DRFM干扰信号的频谱特性,利用脉冲多普勒(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。
Good jamming effect can be achieved by using digital radio frequency memory（DRFM）to replicate and modulate radar signals.This paper analyzes the characteristics of 3 bit phase quantization DRFM jamming signal based on weighting network,brings forward the method of equal mean dispersing to obtain weighting value of weighting network,constructs waveform expression of 3 bit phase quantization DRFM in the time domain,discusses the spectrum characteristics of 3 bit phase quantization DRFM jamming signal,analyzes the DRFM jamming effect by using pulse Doppler（PD）radar model.The simulation proves that DRFM technology has perfect jamming effect to PD radar.
