摘要: 本文详细分析了卫星多波束天线的指向误差对多波束天线的阵列流形和干扰源-定位的影响,并提出一种修正方法,可以在已知天线指向精度的情况下对采用MUSIC算法的得到定位结果进行修正,从而有效提高了卫星干扰源定位的性能.计算机仿真支持了理论分析的结果.

Abstract: This paper presents an analysis of the influence of pointing error on antenna array manifold and performance of interference localization based on a satellite multiple-beam antenna.A modified approach is also presented which can modify the results of interference localization by using MUSIC algrithm and come out with more robust results.Simulation results support the theoretical analysis.

Key words: satellite multiple-beam antenna, interference localization, array manifold, antenna pointing error, DOA estimation1
