Bistatic Scattering and Depth Dependent Gas Fractions in the Acoustic Modeling of Gassy Sediment.
Abstract
A model for acoustic scattering from the seabed was previously developed by Boyle and Chotiros (ARL-TR-93-15, 'Bottom Backscatter from Trapped Bubbles' and ARL-TR-94-21, 'Bottom Backscatter from Trapped Bubbles II'). The model treats acoustic scattering as a sum of three independent processes, including scattering from the sediment interface, volume scattering from sediment grains, and volume scattering from trapped gas bubbles that might exist between grains. Recently the gas bubble component of this model has been modified to allow for bistatic scattering and depth dependent sediment gas fractions. The theories behind these modifications are described, and in each case the character of the resulting model studied. jg
