相关信号DOA估计的超分辨算法及其改进

A Super-resolution Algorithm Which Estimates the DOA of Correlative Signals and Betterment

常见的超分辨算法,如MUSIC算法、Capon算法等,只能对非相关信号到达角进行估计,无法分辨两个相关回波信号。介绍的d-MUSIC算法解决了这个问题,文中给出了这种算法的适用范围和空间谱特性,提出增加泰勒展开阶数的方法来提高算法的测角精度。

The normal super- resolution algorithm -as if MUSIC algorithm and Capon algorithm - can only estimate DOA of the incorrelative signals. They can not distinguish the correlative signals. Introduces d - MUSIC algorithm which solved the problems. We also give the range of the algorithm and the special spectrum performance. Improves its precision through increasing the Taylor expansion order.
