摘　　要：讨论了一种基于遗传算法的综合任意平面阵列方向图的方法。算法直接将复数作为遗传算法的编码，省去了一般遗传算法的编码、解码步骤，简化了计算过程，节约了计算时间。采用两种交叉算子，能够较好地克服早熟收敛和收敛对初始群体的依赖。仿真结果表明，该方法能够对任意栅格阵列实现复杂形状方向图的赋形，并且在实现主瓣赋形的同时能够实现良好的旁瓣抑制。A planar array antenna with arbitrary geometry synthesis technique based on genetic algorithm is discussed. This approach avoids coding/decoding and directly works with complex numbers to simplify computing program and to speed up computation. This approach uses two crossover operators that can overcome premature convergence and the dependence of convergence on initial population. Simulation results show that this method is capable of synthesizing complex pattern shapes of planar arrays with arbitrary geometry and can realize good sidelobe suppression at the same time.
