UNDERWATER ACOUSTIC NORMAL MODE COUPLING DUE TO RESONANT SCATTERING
The scattering of sound from underwater internal waves is investigated using a theory based on coupling between acoustic normal modes. The predictions of the coupled mode theory are tested by numerical simulation using a parabolic equation propagation model that is mathematically dissimilar. Trends seen in the outputs from the computer model are explained by the predictions of the coupled mode theory, illustrating the validity of the coupled mode approach.
