摘　　要：本文建立了卫星平面阵列多波束天线的基本模型,并给出了平面阵列多波束天线的阵元空间和波束空间的基本概念.研究了基于卫星平面阵列多波束天线波束空间的自适应调零和干扰源定位技术并给出了仿真结果.理论分析和仿真结果表明:基于平面阵列多波束天线波束空间的自适应调零和干扰源定位技术可以在卫星通信系统中得以应用,可以极大的提高卫星通信系统的抗干扰能力.This paper presents the model of satellite planar army multi-beam antenna and the concepts of beam-space and element-space. The adaptive nulling and interference localization based on beam-space of satellite planar array multi-beam antenna are investigated and some simulation results are also presented. Theoretic analysis and simulation results show that the adaptive nulling and interference localization based on beam-space of satellite planar array multi-beam antenna can be applied to satellite communication systems and it can increase the anti-jamming ability of satellite communication systems sharply.
