基于独立分量分析的外辐射源雷达主瓣同邻频干扰抑制研究

Recearch of Mainlobe Co-channel Interference Suppression Based on Independent Component Analysis in Passive Radar

主瓣范围内的同、邻频干扰问题是外辐射源雷达的一个难题。针对这一问题,本文提出一种基于独立分量分析的同、邻频干扰抑制方法,在直达波、多径抑制后通过对信号进行独立分量分析,剔除同、邻频干扰。对实际采集数据的处理结果证明了方法的有效性。

The mainlobe Co-channel interference is a noticeable issue in the passive bistatic radar (PBR). To solve this problem, a cochannel interference suppression approach based on the in dependent component analysis is presented. The method exploits the principal components analysis to extract the mainlobe interference components. The effectiveness of the presented approach is proved by the measured data processing results.
