摘要
针对地球静止轨道(GEO)移动通信卫星星上多波束天线波束成形技术,研究了合成多波束对地覆盖、点波束天线增益以及波束间干扰抑制技术。利用仿真分析软件进行多波束天线的波束成形仿真分析,优化了天线系统的设计参数,改善了波束间的隔离度指标,提高了系统通信性能和局部地区的信道容量,完成了地球静止轨道移动通信卫星系统合成多波束天线的设计。
This paper mainly focuses on the technology of the multi-beam antenna on the GEO （Geostationary Earth Orbit） mobile communication satellite. The relative technologies wave studied,including the contour of the satellite composite multi-beam antenna,the gain of the beams and the interference controlling among the beams. With the help of software,some antenna system parameters can be optimized. Consequently,the beams isolation is increased,which improves the whole communication systems capability. Finally,it was realized that the composite multi-beam antenna design on the GEO mobile communication satellite is completecl.
