摘　　要：瞬态干扰的存在会严重影响矢量信号处理方法性能,必须对其抑制。该文提出一种基于偏振分析的瞬态干扰抑制方法。该方法提取矢量信号的偏振参数,构建极化滤波器,对接收信号滤波,去除瞬态干扰。通过极化滤波器的调制函数判断瞬态干扰的存在位置,再利用信号的偏振模型恢复瞬态干扰处信号。仿真结果和实验数据表明该方法可以有效地抑制瞬态干扰。The impulsive interference occurred in the received signals causes bad performance in signal processing. Thus noise should be suppressed. Tn this paper, a novel method based on polarization analysis is proposed to reject transient noise. With the polarization parameters of the vector signals, a polarization filter is built up. When the filter is applied to the received signals, the impulsive interferences are wiped off at the same time. The data segments contaminated by the interference are found out via the modulate function of the polarization filter, and then the polarization model is used to reconstruct the signal segments. The validity of the suggested approach is demonstrated by simulation results and experiment data.
