通信卫星多波束天线的发展现状及建议

Development Status and Proposals for Multi-beam Antennas of Communication Satellites

社会信息化发展促进了个人通信、高速网络、军事通信和移动通信等服务需求的快速增长,也推动了通信卫星向大容量高速率方向发展。星载天线作为通信卫星的关键数据传输终端,采用多波束方案是应对这一发展需求的理想选择。文章对星载反射面多波束天线、相控阵多波束天线,以及波束形成技术进行了分类介绍,并对这些类型的多波束天线在当今通信卫星领域的应用状况及未来的发展趋势进行了分析,最后对星载多波束天线的发展提出了一些建议。

Requirements rising in service of personal communication,high-speed networks,military communication and mobile communication,as well as the communication satellite's development towards large capacity and high speed are promoted by the development of the social informatization. As the key terminals of the data transfer on communication satellites,it is ideal to adopt the scenario of Multi-beam Antennas( MBA) to meet the development requirements. The introductions of reflector MBA,phased-array MBA,and beam forming techniques are presented in this paper. Along with an analysis of the current application situation and the development trends for MBA of the communication satellites are illustrated. Finally,some proposals on the developing of MBA of satellites in China are proposed.
