摘　　要：针对区域覆盖低轨卫星移动通信系统星座,提出了一种改进遗传算法(GA)的优化设计。根据改进的区域覆盖星座模型,采用可变维数优化的整数与实数混合的染色体编码。给出了算法步骤。某区域覆盖低轨卫星移动通信系统星座优化设计算例结果显示了该算法的有效性。An optimal design based on the improved genetic algorithm for LEO regional coverage mobile satellite communication system was put forward in this paper. According to the modified regional coverage constellation model, a variable dimension mixed binary and real coding was adopted. The algorithm＇s steps were presented. The design of some LEO regional coverage mobile satellite communication system showed that this algorithm was effective.
