| 摘 要： | 针对阵元之间存在互耦误差,阵列流型会出现一定程度的偏差和扰动的问题,提出了基于MUSIC(MUlti-ple SIgnal Classification)迭代法的互耦误差自校正算法及在互耦误差条件下的DOA(Direction of Arrival)估计算法。利用MUSIC迭代法对波达方向和互耦误差同时进行估计。该算法能够在互耦误差存在的情况下,有效地估计出波达方向和互耦矩阵,仿真实验证明了该算法的有效性。

| Abstract: | Aiming at the problem that the mutual coupling error among array elements can make a certain degree of deviation and perturbation appear in the array manifold,a mutual coupling error self-correction algorithm based on MUSIC iteration method and a DOA estimation algorithm under the condition of mutual coupling error are put forward in this paper.The MUSIC iterative method is used to estimate the direction of arrival and mutual coupling error at the same time.The algorithm can estimate the direction of arrival and mutual coupling matrix effectively under the condition of mutual coupling error,and the results of simulation experiment show the effectiveness of the proposed algorithm. |
