英文摘要：

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.
