摘　　要：基于同步轨道星载多波束天线,开展了波束合成技术研究。首先,提出了波束合成的模型,对影响波束合成的主要因素进行了理论分析;其次,结合25m反射面、7馈源的天线模型,进行了波束合成性能的仿真分析;结果表明,采用多波束合成技术可以显著改善大反射面多波束天线的增益性能。Base on the multi-beam reflector antenna which equiped on the GEO satellite, The research of the technology with beamforming is implemented in this papero Fisrtly, the model of beamforming is given, then the factors which influence beamforming are analyzed. Combinate with 25m reflector and 7 feeds antenna, this paper simulates the efficiency of beam_forming. The result shows that multi-beam forming can improves the gain of multi-beam reflector antenna evidently.
