| 摘 要： | 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。

| Abstract: | 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. |
