2-D DOA Estimation of Quasi-Stationary Signals via Tensor Modeling

Abstract:

A two-dimensional direction-of-arrival estimation of quasi-stationary signals via tensor modeling using an L-shape array is presented in this paper. This is a novel approach which is an extension of Khatri-Rao subspace approach, denoted by extended Khatri-Rao subspace approach. The proposed approach can work even when number of sensors is less than number of sources. To utilize the multilinear algebra, direction of arrival (DOA) is developed in the multidimensional sense. The effectiveness of the proposed method is verified through numerical examples.
