In this paper, we propose a two-dimensional (2-D) angles of arrival (AOAs) estimation method based on a joint diagonalization of two spatio-temporal (ST) correlation matrices. The mathematical manipulations proposed in this paper take the structure of the array that enable estimating 2-D AOAs simultaneously without 2-D searching or pairing. The performance comparison shows that the proposed method is better than ST-DOA matrix method.
