| 摘 要： | 基于自适应天线阵理论,研究共形阵的赋形算法,给出一种用于圆柱形阵列天线三维方向图的波束赋形算法。该方法通过迭代获得一组最优阵元激励幅相加权值,可以同时控制阵列波束的方向、形状和副瓣电平。通过圆柱形阵列的仿真计算得到满足设计要求的三维平顶波束和余割波束方向图,证明这种算法的有效性。

| Abstract: | A 3D pattern synthesis method for cylindrical arrays based on adaptive array theory are presented in this paper. With this algorithm, the values of the weighting function are iterated to minimize the absolute difference between desired and achieved main-lobe patterns and obtains lower desired side-lobe levels. With the simulation of cylindrical array, the patterns of flat top beam and cosec beam are gained. Example simulation are shown to illustrate the effectiveness of the algorithm. |
