Two-dimensional DOA Estimation in Monostatic MIMO Radar with Double Parallel Uniform Linear Arrays using Propagator Method

In this paper, we propose a low complexity two-dimensional direction of arrival (2D-DOA) estimation in mono static multiple-input multiple-output (MIMO) radar with double parallel uniform linear arrays. The proposed algorithm uses propagator method (PM), which does not require any eigen-value decomposition of the covariance matrix and singular value decomposition of the received data, obtains closed-form solution of 2D-DOA, and has very close angle estimation performance to estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm Our algorithm can estimate azimuth and elevation angles without additional pair matching in mono static MIMO radar. Simulation results verify the usefulness of our algorithm
