SPATIAL SPECTRUM ESTIMATION TECHNIQUES FOR SATELLITE INTERFERENCE LOCALIZATION

Wang Huali Gan Zhongmin (Institute of Communications Engineering PLAUST,Nanjing 210016)  
It is an important aspect for communication satellite interference localization technques to obtain the source’s direction-of-arrival(DOA)information based on multiple beam antenna(MBA).This paper presents a brief overview of interference localization techniques for satellite communication system,and then focuses on spatial spectrum estimation method applied to the localization of radio frequency interference(RFI)sources.The feasibility of the proposed method is further verified by the simulation results of the MUSIC algorithm when used with MBA model.
