Xu Minchao, Qing Li, Long Wen-wu, Zhao Sanwei, Yuan Jingang

Abstract

This paper elaborates the working principle of traditional spatial sidelobe cancellation (SLC), and introduces its limitation in adaption to the multipath effects of interference source by measured data processing. Through analysis of the relationship between multipath interference and radar antenna, a method is proposed to suppress interference by combination of time and spatial domains based on the extensive cancellation algorithm. Analysis of measured data shows that this method can effectively suppress the multipath effects of interference.
