Description In this paper a study is initiated to observe the usefulness of directional spectral estimation techniques for underwater bathymetric applications. High resolution techniques like the Maximum Likelihood (ML) method and the Maximum Entropy (ME) method are used for 16- element linear arrays and compared with existing 60- elements array using the Bartlett method. The beampattern computations using the ML and ME methods under flat bottom conditions reveal the usefulness of the high resolution methods. The study also considers the multiple source/interference condition, i.e. the situation for rough terrain as well as artifact-creating conditions. The superiority of the high resolution methods are observed in an examination of the beampatterns. The conditions of widely and closely separated coherent/incoherent sources are also examined
