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.
