面向大规模星座的多波束测控天线及应用

Multiple-beam TT&C antenna and its application for large scale satellite constellation

大规模卫星星座的出现给传统测控模式带来了巨大挑战。利用机械扫描式的测控天线对卫星进行的一对一测控已不能很好满足大规模卫星星座的测控需求,具备快速指向能力的多波束测控天线是解决大规模星座测控的有效手段。通过对国内外多波束测控天线的调研,介绍了多波束测控天线的发展概况,对其技术特点进行了分析和研究,指出了多波束测控天线在星座测控中的优势,并提出基于多波束测控天线的星座测控建议。

The emergence of large-scale satellite constellation has brought great challenges to the traditional TT&C mode.The method using mechanically steered reflector antenna for peer-to-peer TT&C between ground station and satellite can't perform well for the large-scale satellite constellation while multiple-beam antenna with electrically steered capability can be the potential effective measure.Firstly,this paper investigates the multi-beam TT&C antenna at home and abroad and introduces their development status,then analyzes their technology character and indicates its significance for constellation TT&C.Finally,the advice on TT&C scheme for constellation is proposed based on multiple-beam TT&C antenna.
