| 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. |
