Scattering of High-Frequency Acoustic Energy from Discrete Scatterers on the Seafloor: Glass Spheres and Shells

摘要

Shells and shell debris are common at the water/seafloor interface. Quantifying the scattering from shells is thus important for predicting high frequency backscattering from the seafloor. A backscattering experiment is described in which glass beads (radius equal to 1.75 cm) and shells (largest dimension tip to about 10 cm) were placed near a bottom-mounted sonar and backscattering examined as a function of the number of discrete scatterers Supported by Office of Naval Research - USA.
