Underwater Acoustic Backscattering and Echo Structure Characteristics for a Thin Stiffened Plate.

Abstract

This report describes an experimental investigation of the underwater acoustic reflection characteristics of a thin stiffened aluminum plate. Based on ray theory and echo structure analysis, an attempt was made to show that the presence of a reinforcing rib can be acoustically predicted in time. Good agreement between theoretically predicted and experimentally measured echo components was achieved. (Author)
