Hatem Changuel, Ferid Harabi, Ali Gharsallah · Electromagnetic waves · 2006
This paper proposes a computationally efficient method for a two-dimensional direction of arrival estimation of multiple narrowband sources.We apply the MUSIC method which requires eigenvalues decomposition to the cross spectral matrix.This paper will employ two L-shape arrays that showed better performances than the one L-shape and the parallel shape arrays.In spite of its computational complexity, simulation results verify that the proposed subspace technique gives much better performance than the propagator method.
