摘要

在本文中,我们提出了一种数据自适应方法来估计相关和/或相干源的空间频谱。该方法让人想起MVDR/Capon波束形成器,但产生多维空间响应,每个被检查的源都有一个维度。估计到达方向(DOA)在多维空间响应中作为能量集中点给出。数值算例表明,与标准的MVDR/Capon波束形成器相比,该波束形成器有了显著的改进。

A Capon-like spatial spectrum estimator for correlated sources
In this paper, we propose a data-adaptive method for estimating the spatial spectrum for correlated and/or coherent sources. The method is reminiscent of the MVDR/Capon beamformer, but yields a multidimensional spatial response with a dimension for each examined source. The estimated directions of arrival (DOA) are given as the points of energy concentration in the multidimensional spatial response. Numerical examples indicate a significant improvement over the standard MVDR/Capon beamformer.
