| 摘 要： | 在相干信号存在的情况下,MUSIC算法失效,修正MUSIC算法却适用。但是,在角度间隔很小的情况下,修正MUSIC算法的测向性能会下降甚至失效。对修正MUSIC算法作出改进,通过利用接收信号的互相关矩阵信息,提高整个数据自相关矩阵的信息利用率。在角度间隔很近的情况下,该方法比修正MUSIC方法有更好的测向性能。最后,给...

| Abstract: | 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.Fi... |
