Estimation Algorithm of Two-Dimensional Direction of Arrival Based on Rectangle Array of Distributed Source

Abstract

For estimating two-dimensional direction of arrival (DOA) of local scattering distributed source, the computational complexity of various algorithms for DOA is prohibitively high, induced by high dimension searching manipulation. According to this problem, an ESPRIT-like algorithm is proposed. The proposed algorithm exploits the rotational invariance properties of signal space, the DOA can be obtained without any peak-finding searching, which has significantly reduced the computational complexity. Simulations clearly demonstrate that the algorithm enjoys improved precision, and is more suitable for complicated environment.
