Three-Dimensional Direction of Arrival Estimation of Sources in Impulsive Noise Environments

In Impulsive noise environments, the three-dimensional multiple signal classification (3D-MUSIC) algorithm would lose robustness to 3D direction of arrival (DOA) estimation of sources. In this paper, the correntropy-based correlation and correntropy-based operator replace the uniform circular array covariance matrix of 3D-MUSIC, respectively, which achieves 3D-DOA estimation in impulsive noise environments. The simulations indicate that the two proposed methods are effective.
