Bistatic Acoustic Scattering from Munitions: Interactions with Nearby Clutter and the Water-Sediment Interface

Abstract

The first year of MR19-1234 saw progress on four tasks: (1) bistatic scattering, (2) multiple scattering from targets in the free field, (3) frequency dependent beam patterns, and (4) reverberation from small-scale surface roughness. Each of these tasks required modifications to or improvements in the implementation of the target-in-the-environment response (TIER) model. As part of the work on the TIER model, the numerical implementation was refactored to permit a straightforward integration of multiple scattering. These tasks are described in the following document.
