| 摘 要： | 在各阵元增益不一致条件下,模型误差导致波达方向(DOA)估计性能恶化.Weiss等研究了一种对增益幅度误差不敏感的一维搜索估计方法,但存在DOA估计的模糊性问题.本文在增益幅度未知条件下,提出了一种新的基于广义特征值分解的DOA估计方法,并给出了模糊性问题分析、解模糊性方法及仿真实验结果.

| Abstract: | Recent studies have shown that performance of MUSIC or other algorithms degrades drastically and even fails with a bad knowledge on array manifold.An approach based on 1-dimensional searching for DOA estimation with unknown intensity coefficients was presented in 1].The ambiguous peaks appearing in certain cases must be eliminated.In this paper,a new method based on generalized eigenvalue decomposition is proposed.Detailed analysis of ambiguous problem is presented and is illuminated by numerical examples. |
