Summary:
A one dimensional (1D) based tree structure algorithm is proposed for the estimation of azimuth and elevation angles of the signals received by a uniform rectangular array (URA). The proposed algorithm successively apply several times of 1D-MUSIC algorithm, in tree structure, to estimate the azimuth and the elevation angles independently. Subspace projectors are exploited in conjunction with the 1D MUSIC algorithms to decompose the received signal into several signals each coordinated by its own 2D-DOA. The pairing of the azimuth estimates and the associated elevation estimates is naturally determined due to the tree structure of the algorithm.
