| 摘 要： | 本文提出了到达波方向(DOA)估计的一种新算法。基于信号特征向量分解的一种唯一形式,我们提出了用递推算法来实现由一个或几个信号特征向量进行DOA估计。与一般的特征结构法相比,该方法不但可以解决相干源问题而且改善了在低信噪比情况下的估计性能,并具有使用灵活的特点。计算机仿真证实了上述结论。

| Abstract: | In this paper, a new algorithm for direction of arrival (DOA) estimation is presented. Based on the unique decomposition of signal eigenvectors, we use one or more signal eigenvectors to estimate DOAs by an iterative algorithm. Compared to eigenstructure method, the paper's algorithm is valid for any cases whether the sources are coherent or not. It also has a significant improvememt in estimate performance at low SNR and has a more flexible form for implementation. Computer simulations have shown the effectiveness of the algorithm. |
