Presentation title: Modeling and experiment of ocean reverberation in the range-dependent environment
Summary of the presentation: Ocean reverberation is an important issue in underwater acoustics due to the significant influence on the working performance of active sonar. A coherent reverberation model based on the adiabatic-mode theory for range-dependent shallow-water environment is developed. The presented model is verified by reverberation observation in the shallow-water experiment. In deep water, we develop a reverberation model based on the ray theory, which can accurately calculate monostatic and bistatic reverberation intensity. The non-stationary characteristic of deep-water reverberation loss is well explained by the model.
