Description: 主要目的都是为了弥补各种算法的不足，发挥各种算法的优势，实现扬长避短的初衷。然而稍显不足的是，这些算法目前主要集中在解决阵列的二方向图波束赋形，例如笔形波束、平顶波束、余割波束等。实际上，共形阵方向图综合是一个三维优化问题，仅仅用二剖面赋形结果代替实质上的三维优化，难免与最终的实际情况有所差异。尤其是共形球面阵的波束成形问题，用二优化算法显然有些无能为力，比如空间波束指向就是一个三维问题。因此，本文研究了一种共形球面阵天线的三维方向图综合算法。-The main purpose is to compensate for the lack of various algorithms take advantage of a variety of algorithms to achieve weaknesses in mind. However, slightly less than that, these algorithms currently focused on solving two patterns beamforming array, such as pencil beam, flat beam cosecant beam and so on. In fact, the conformal array pattern synthesis is a three-dimensional optimization problem, just replace the three-dimensional optimization essentially shaped cross-section with two results will inevitably differ the ultimate reality. Especially conformal spherical array beamforming problem with two optimization algorithm appears to be some powerless, such as space is a three-dimensional problem of beam pointing. Therefore, this paper, a total of three-dimensional shape of spherical array antenna pattern synthesis algorithm.
