Abstract :
A new two-dimensional direction of arrival (2D DOA) estimation method is proposed, in this paper. The presented method makes using of blind source separation method based on the second-order identification to estimate the array response matrix. Via the rotational invariance techniques, we can estimate the 2D DOA from the array response matrix estimation. The estimated elevation angles and azimuth angles is automatically determined. Simulation results are presented verifying the efficiency of the proposed method.
