摘　　要：在概述数字波束零点形成加权结构的基础上,给出了幅度相位加权、仅相位加权和混合控制加权三种算法,并进行了比较:幅度相位加权方法形成零点的效果最好,但算法比较复杂;仅相位加权算法运算简单、有利于硬件实现,但只在零点处于特定位置时效果较好;混合控制加权算法实现灵活,但对受控阵元位置要求较高,具有较强的发展潜力。文中最后采用计算机仿真验证了理论分析结果。On the base of summarising the digital beam null forming weighting structure, this paper presents three kinds of algorithms： amplitude and phase weighting, only phase weighting and compound control weighting, and then compares the three kinds of algorithms. The best algorithm is the amplitude and phase weighting one, but it is complicated. The only phase weighting one is easy to hardware realization, but it is only effective at limited particular null location. The compound control weighting algorithm is vivid and has strong developing potential, but it needs appropriate location of controlled cells. The computer simulation verified the analysis results in the end.
