摘　　要：随着极地科考活动的逐年增加,极地用户与境内的卫星通信需求也越加旺盛,但是现有技术还不能很好地满足。相比地球静止轨道(Geostationary Orbit,GEO),倾斜地球同步轨道(Inclined GeoSynchronous Orbit,IGSO)卫星具有两极覆盖性好的优点,设计了一种基于IGSO卫星的Ka多波束极地通信系统,重点给出了其中Ka多波束天线的设计和分析方法。系统可在极地形成大范围的多波束覆盖,支持多个散布用户的接入,并具有波束在轨重构能力,通过单波束提供更高的通信速率。With the increase of the scientific activities in polar regions year by year,the demand of satellite communication between users and domestic stations growing rapidly,but the current technology did not match these demand yet.Different to Geostationary Orbit(GEO),Inclined GeoSynchronous Orbit(IGSO)satellites have an advantage of coverage at polar regions,so an IGSO multi-beam satellite telecommunication system is proposed for polar regions,as well as the design and analysis method of the Ka multi-beam antenna is given.This system could provide a multi-beam coverage for a large region and allow distributed users access to satellite service,and beams could be reconfigured to a single beam in orbit to enhance the communication rate.
