摘要: 首次采用遗传算法对卫星多波束天线的赋形问题进行了研究,根据地面接收电平的不同要求, 以整体偏差逼近和偏差最大点的逼近为目标建立了两种适应度函数,对中国版图进行赋形,得出了不同的赋形效果,并分别与FP及Minimax方法作了比较,说明遗传算法用于多波束赋形天线的优化是切实可行的,且寻优能力较强.

关键词: 多波束天线, 优化, 遗传算法

Abstract: Firstly GA is applied to study multi-beams shaped antennas.Due to different desired power requirement, two different fitness functions are formed to minimizethe power deviation of the whole sample points or of the worst sample point.Then GA's are applied to contour China map in contrary to FP method and Minimax method, which proves that GA's are feasible and powerful to investigate the optimization problems in multi-beams shaped antennas.

Key words: multi-beam antennas, optimization, genetic algorithms
