摘　　要：相干信号源的存在使得很多经典的高分辨算法受影响甚至失效。基于对去相干处理的方法的研究,发现两种算法具有较好的去相关效果——修正的MUSIC算法即MMUSIC和加权前后向空间平滑算法。这两种方法的本质都属于算法MUSIC的改良,它们之间有一定的联系。通过计算机仿真对它们进行比较,发现前者具有更好的去相关性能,而且对阵列没有孔径损失。The existence of coherent signal source makes a lot of classic high-resolution algorithm affected or even failure.Based on coherent processing method to study found that the following two algorithms related to a better effect,that is,as amended MUSIC algorithm - MMUSIC and the weighted spatial forward backward smoothing algorithm,these two methods belong to the essence of the algorithm MUSIC modified,and they have some links.Through computer simulation and then compare them,found that the former has a better correlation to performance,but no aperture arrays loss.
