摘　　要：利用杂草入侵算法对线阵天线进行方向图可重构优化,在未给定阵元公共幅值的情况下,对激励幅值和相位同时优化,通过改变加权相位分别实现余割波束和笔状波束赋形。仿真结果得到较低的峰值旁瓣电平及较好的波束形状,表明了该算法是有效可行的。Invasive weed algorithm is used in pattern reconfigurable optimization for linear antenna array . Without the given common amplitude of antenna element, the amplitude and phase of excitation are simultaneously optimized to obtain cosecant beam and pencil beam by changing the weighted phase, and the lower peak sidelobe levels and the better beam shape are obtained to meet the design request. Simula -tion results prove that the employed method is feasible and efficient.
