Studying Shallow Water Environmental Acoustic Fluctuations with Broadband Measurements, and Fluctuations & Invariants in Shallow Water

Abstract

This report describes the research performed on behalf of the Office of Naval Research on Waveguide Invariants, Fluctuations and noise, and the study of feedback noise phenomenon in shallow water. The results showed both theoretically and experimentally there was a spectral focusing when propagation paths transitioned from one type to another. Additionally, the robust presence of the invariant theory in shallow water broadband data was demonstrated experimentally.
