说明：  基于模拟退火算法的优化波束设计方法，思想是根据特定场合对波束的要求，按照给定的波束优化指标，通过建立目标函数，利用模拟退火算法对波束的加权系数进行全局寻优，从而达到波束优化的目的
(The idea of optimizing beam design method based on simulated annealing algorithm is to use simulated annealing algorithm to optimize the weighted coefficient of beam globally by establishing objective function according to the requirements of beam in specific occasions and given beam optimization index, so as to achieve the purpose of beam optimization)
