摘　　要：近年来,随着人们对卫星通信需求的不断提高,多点波束卫星通信系统被提出。相比于传统区域波束,多点波束卫星通信采用频率复用,提高了信道利用率,每个波束的G/T值更高,但多点波束卫星通信系统面临的最核心的技术点就是跨波束切换问题。文章对高速移动终端卫星通信的波束切换进行分析研究,实现了一种高速移动终端基于信道信号强度自主决定切换时机和选择目标波束的切换策略。In recent years,with the increasing demand for satellite communication,multi beam satellite communication system has been proposed.Compared with traditional area beam,multi beam satellite communication has improved channel utilization and frequency reuse,and the G/T value of each beam is higher.However,the core technology of multi beam satellite communication system is the corss-beam switching problem.In the paper,the beam switching of high-speed mobile terminal satellite communication is analyzed and studied,and a strategy of beam switching based on the signal strength of channel is implemented to determine the switching time and select the target beam.
