摘　　要：为解决干扰方位微变与零陷方向固定的矛盾,提出了一种基于最大信噪比(MSNR)准则的零陷宽度、深度控制方法,通过加大零陷范围和加深零陷深度来抑制全部干扰信号,并提高了系统干噪比。仿真结果验证了方法的有效性,并分析了该方法的适用范围。To solve the inconsistency between jamming azimuth differential and fixed null steering direction,this paper puts forward a control method of null steering width and depth based on maximum signal-to-noise ratio（MSNR）rule.By increasing null steering range and deepening null steering depth,the jamming signals are suppressed entirely,and the jamming-to-noise ratio of system is improved.The simulation result validates the validity of the method,and analyzes the application range of the method.
