摘　　要：针对传统多波束形成不能有效抑制干扰信号的问题,研究了几种发射自适应置零数字多波束形成算法,包括线性约束最小方差算法、正交投影算法、导数约束加宽零陷算法等,同时对这些算法进行了仿真对比分析,发现每种波束形成算法各自的优缺点,针对实际工程应用中不同的情况,提出了对应的解决方案。As to the problem that traditional transmitting digital multi-beam forming can not effectively suppress the interfering signals,this paper studies several kinds of transmitting adaptive nulling digital multi-beam forming algorithms,including linear constrained minimum variance algorithm,orthogonal projection approach and derivative constraint wide nulling algorithm,etc.Simultaneously,these algorithms are compared and analyzed through simulation.The result shows that each algorithm has respective advantages and disadvantages,then corresponding solutions are proposed for different situations in actual engineering application.
