摘　　要：主瓣干扰是雷达面临的主要干扰,基于滑窗的幅相重构主瓣干扰抑制方法通过幅度滑窗估值重构干扰信号,实现对干扰的对消。针对基于滑窗的幅相重构方法,仿真分析滑窗长度对干扰抑制性能的影响,并给出了窗长选择的推荐值。Main lobe interference is the main interference faced by radar.The amplitude and phase reconstruction main lobe interference suppression method based on sliding window reconstructs the interference signal through amplitude sliding window estimation to realize interference cancellation.Aiming at the amplitude-phase reconstruction method based on sliding window,the influence of sliding window length on interference suppression performance is simulated and analyzed,and the recommended value of windowlengthselection isgiven.
