In direction of arrival estimation, the signal sources are usually assumed to be point sources. If the signal sources are dispersive, however, direction of arrival estimation methods based on the point source assumption may result in poor performance. In this paper, we consider direction of arrival estimation under a parametric dispersive signal modeling. An estimation method based on the well-known conditional maximum likelihood method in the parametric model are considered.
