Large Aperture Acoustic Arrays in Support of Reverberation Studies
Abstract
In preparation for a major field experiment this report addresses the development of acoustic arrays which are needed in order to make carefully controlled and well-documented measurements of bottom reverberation. The purpose of these measurements is to study the physics of the backscattering process and to quantify backscattering characteristics as a function of physically meaningful parameters (e.g. ensonified area, grazing angle, bottom material properties, bottom roughness, etc.). Specific array systems which are addressed include the following: (a) towed horizontal array, (b) horizontal and vertical array, (c) ship-tethered 64-element vertical array, and (d) self-contained, 16- element vertical array.
