Abstract:

The goals include development and refinement of tomographic algorithms with applications to the quantitative measurement of bubble fields. Natural bubble fields have a profound effect on sonar systems while ship wakes have a debilitating impact on the effectiveness of anti-torpedo torpedo systems. This research investigates the use of acoustic tomography and effective medium models for wave propagation in bubbly water as a means of determining physical properties of bubble fields.
