摘　　要：对俯仰面波束需要赋形的阵列天线进行了分析和设计。采用数值方法对阵列天线的方向图进行了综合,将平均偏差用于目标函数的构造之中,同时结合工程实际,给出了约束条件。通过优化目标函数,得到所需的单元馈电电流。天线的实测方向图完全符合赋形波束的要求,表明该设计方法是可行的。The analysis and design of an array antenna with beam shaping in vertical plane is introduced in this paper, and the numerical method is adopted in synthesizing the radiation patterns. Based on the mean deviation and project practice, the object function and constraints are presented respectively. By optimizing the object function, the feeding currents of column are obtained. The measured radiation patterns satisfy the requirements of beam shaping well, which demonstrates the effectiveness of this approach.
