Abstract: To estimate the 2D DOA(direction of arrival) of local scattered signals, a novel algorithm is suggested on the basis of L-shape array of coherently distributed source by way of reducing the steering vectors from coherently distributed source in form of integral to the Schur-Hadamard product of the steering vector from point source and real vector. Then, taking advantage of the array configuration to estimate the elevation angle, the azimuth angle is estimated using the second-order statistics based on Schur-Hadamard product. But the proposed second-order statistics is insensitive to white noise, so the SNR performance is improved. By the new algorithm the 2D-DOF joint operation is reduced to a two-step one-dimensional estimation problem, so as to reduce efficiently the computation. Simulation test shows its validity.
