Shallow-water Reverberation: Measurement Technique, Initial Reference Level and Geoacoustic Inversion.

摘要

The long-term goals of this work are: to develop a practical model for predicting reverberation level (RL), echo-reverberation ratio and reverberation vertical coherence (RVC) in shallow water; to characterize seabottom geoacoustic parameters (sound speed and attenuation) and scattering function from high quality reverberation data in a frequency range of 100- 3000Hz, and to reveal the physics of bottom scattering from the 'window' of shallow-water reverberation.
