摘　　要：噪声调频干扰属于压制式干扰,由于它容易达到宽的干扰带宽,已经成了目前噪声干扰的主要形式。通过时域自相关法对噪声调频干扰进行频谱分析,简要说明其干扰特性和中放输出的干扰特性,最后建立噪声调频干扰信号及其通过中放后的时间序列模型。Noise frequency modulation (FM) jamming, which belongs to blanket jamming, is already become the main form of noise jamming at present, because the wideband was gained by it. The spectrum of noise FM jamming is analyzed by time domain autocorrelation method in this paper. It's jamming peculiarity and IL outputting signal's jamming peculiarity are explained. At last, these time series models of noise FM jamming signal and IL outputting signal are built.
