Abstract
Direct measurements of acoustic scattering from the seabed at shallow grazing angles presents a considerable challenge in shallow water. Specifically, returns from the air-water interface typically contaminate the signal of interest. To address this issue DREA has developed a pair of sea going research systems for measuring acoustic scatter from the seabed in shallow water environs. In this paper the acoustic attributes of both systems will be outlined, the experimental geometry will be described and measurements of acoustic backscatter and forward scatter collected during one such experiment will be presented.
