提出了一类适用于Alpha稳定分布随机变量的统计量—类M估计相关(MELC),通过构造阵列输出的类M估计相关矩阵,提出了适用于Alpha稳定分布噪声环境下的波达方向(DOA)估计新算法,即MELC-MUSIC算法。仿真实验表明,在Alpha稳定分布噪声环境下,MELC-MUSIC算法在抗噪声特性、多源信号分辨性以及对不同形式信号(圆对称信号或非圆对称信号)的适应性方面获得比基于分数低阶统计量(FLOS)的MUSIC方法更好的估计性能。

In this paper, we consider the source localization for a mixed near-field (NF) and far-field (FF) narrowband signals impinging on a uniform linear array (ULA) with the symmetrical geometric configuration. A computationally efficient direction-of-arrivals (DOAs) and range estimation method for the mixed NF and FF signals is proposed, where the DOAs of the NF and FF signals are estimated separately, and the computationally burdensome eigendecomposition is avoided. Comparing to some existent method

基于天线阵列协方差矩阵的特征分解类DOA估计算法中,多重信号分类(MUSIC)算法具有普遍适用性,只要已知天线阵的分布形式,无论直线阵还是圆阵,不管阵元是否等间隔分布,都可以得到高分辨率的估计结果。
