摘要
随着Ka频段卫星通信系统的逐步建立与普及,为获得更多的通信资源,需要建立更高频段的EHF频段卫星系统,该频段的射频器件、卫星链路等相比传统卫星通信系统均有其自身特点,是未来设计EHF卫星系统必须考虑的问题。文章分析了典型卫星链路和链路中各环节需要的关键技术。
With the gradual establishment and popularization of Ka-band satellite communication system, more EHF band satellite systems need to be established in order to obtain more communication resources. Compared with the traditional satellite communication systems, radio frequency devices, satellite links in EHF band and other have their own characteristics and are the issues that must be considered in future design of the EHF satellite system. This article analyzes the typical satellite link and analyzes the key technologies needed in the link.
