利用遗传算法优化一维线阵电流幅值的结果，结合单波束形成原理以及叠加原理最终成功实现了一维、二维、三维天线阵的超低副瓣多波束的形成问题。通过matlab编程仿真，结果显示设计效果非常好，波束方向，波束相对大小要求均能很好控制。该文对多波束天线的设计具有重要的指导作用。

Based on genetic algorithm ,theory of single-beam forming and superposition principle ,a new way of multi- beam forming with low sidelobe is proposed . The result of matlab emulator shows that this way is efficient and the direction and size of beam can be controlled very well.
