【摘要】 多波束卫星通信系统旨在提供覆盖一定区域的宽频带和高速率的服务,其通过频率复用成倍的提升通信容量,并通过配置窄点波束使地面终端小型化,这大幅降低了系统的成本和复杂度。多波束卫星通信系统核心是波束形成技术。本文介绍了多波束卫星通信系统的发展趋势,又介绍了两种波束形成技术,分别是星上波束形成技术和地基波束形成技术,在分析两种技术的优缺点后提出了一种星地一体的混合波束形成技术。更多还原

【Abstract】 Multi beam satellite communication system is designed to provide services covering a certain area with broad band and high rate,it improves the communication capacity by frequency reuse,and reduces the ground terminal by configuring the narrow beam,These greatly reduce the cost and complexityof the system.Beam forming technology is the core of multi beam satellite communication system.In this paper,the development trend of multi beam satellite communication system is introduced,furthermore,the technology of on-board beam forming and on-ground beam forming are analyzed in detail,finally,according to the advantages and disadvantages of the two technology,this paper introduces the technology of hybrid OBBF/OGBF.更多还原
