基于盲源分离的同频信号测向算法研究
Research of the Same-frequency Signal Direction-finding Processing Based on Blind Source Separation Algorithm
摘要
Abstract
In signal direction-finding system,the MUSIC algorithm is usually used in the direction-finding processing of the same-frequency signal.However,in the actual use of the process,signal subspace and noise subspace are not completely orthogonal,which makes the accuracy and stability of MUSIC algorithm sharply attenuate.Aiming at this problem,the blind source separation algorithm is introduced into the same frequency signal direction-finding system,The blind source separation algorithm is used to deal with the signal,separate the spatial information of each source and complete the direction-finding processing of each source,which could ensure the anti-interference performance of direction-finding system,and increase the accuracy and stability of system,in the situation that signal subspace and noise subspace are not completely orthogonal.关键词
