This paper presents a new subspace-based 2D direction of arrival (DOA) estimation algorithm for narrow-band sources with high-resolution localization capabilities. DOA estimation is achieved by using the noise-subspace eigenvectors of a new extended correlation matrix (ECM). A 2-L-shape antenna array is proposed. Unlike common planar and circular arrays, the novel antenna array with this special geometry requires no pair matching between the azimuth and elevation angle estimation. The performance of the proposed approach is examined by a simulation study in the presence of multiple wave fields. The simulation results show a good estimated performance of the proposed method.
