Abstract

A bistatic seabed scattering measurement technique is described using a towed source (1600-3500 Hz) and towed array in close proximity to the seabed probing vertical angles from 6-20° and bistatic angles from 126-160°. The data strongly support sediment volume scattering as the mechanism that controls the seabed scattering at 2400 Hz across the entire measured angular range; no free parameters are required to make this determination. Since the measured vertical angular range tends to control long-range reverberation (which is generally controlled by steeper angles than propagation due to the shape of the scattering kernel) the results indicate that long-range reverberation in this area would be controlled by sediment volume and not interface scattering. This conclusion is in agreement with other analyses of long-range reverberation measurements in this area.
