The Energy Flux Method for Reverberation: Modeling and Inversion

Abstract

The long-term goals of this work are: (1) to develop a reverberation model for predicting the reverberation level and the echo-to-reverberation ratio in shallow water (SW), and (2) to characterize the seabed scattering in a frequency band of 100-3000 Hz from long-range broadband reverberation measurements. The scientific objectives of this work include: (1) to integrate the energy flux method for SW reverberation with physics-based seabed scattering models for reverberation prediction and inversion, and (2) to analyze the mechanisms of low-frequency (LF) seabed scattering, obtained from reverberation data and the Biot seabed geo-acoustic model.
