A scaled tank experiment for layered stochastic rough interface scattering reflection coefficient

Abstract

The stochastic reflection coefficient of the seabed holds valuable acoustic information about the seabed, making it vital for seabed parameter detection. Therefore, it is crucial to achieve some improved results. In this study, we utilized the small-slope approximation method to obtain the fluctuation characteristics of the reflection coefficient for a layered medium with rough interface. Moreover, we addressed the changes in grazing angle by combining the stochastic rough interface scattering with the layered medium reflection. Initially, we present a simulation result, and subsequently, we conducted a scaled tank experiment to verify the variation characteristics of the reflection coefficient. These findings can serve as a theoretical reference for future seabed exploration.
