An Improved Direction-finding Method of Modified MUSIC Algorithm
Wei Hong · Shipboard Electronic Countermeasure · 2011
When the correlative signals exist,the modified MUSIC algorithm works but the MUSIC algorithm doesn't.However,with very small angle interval,the direction-finding performance of modified MUSIC algorithm will fall even false.This paper improves the modified MUSIC algorithm,increases the information utility rate by using cross-correlation matrix information of received signals.This method has better direction finding performance than the modified MUSIC algorithm in the case that the angle interval is small.Finally,the computer simulation result and performance analysis are presented,which validates the validity of the method.
