In some real surroundings, signal source localization can more adequately be accomplished with distributed source models. When the signal sources are distributed over an area, we cannot directly use well-known DOA estimation methods, because these methods are established based on the point source assumption. In this paper, we propose a two-dimensional distributed signal source model. Then, we address the estimation of the elevation and azimuth angles of distributed sources based on the proposed model.
