Abstract

A new computationally efficient algorithm-based propagator method for two-dimensional (2-D) direction of- arrival (DOA) estimation is proposed, which uses two parallel uniform linear arrays. The algorithm takes advantage of the special structure of the array which enables 2-D DOA estimation without pair matching. Simulation results show that the proposed algorithm achieves very accurate estimation at a computational cost 4 dB lower than that of standard methods. [ABSTRACT FROM AUTHOR]
