Acoustic Resonance Classification of Swimbladder-Bearing Fish at Multiple Scales

Abstract

Accurately describe the spatial and temporal distributions of fish and quantify the mid-frequency clutter characteristics of fish. To conduct a new class of quantitative acoustic studies of scattering by swimbladder-bearing fish utilizing new broadband-acoustic technology that is optimized for use in the resonance scattering region of fish. The studies, which include use of a long-range horizontal-looking system and a shortrange downward-looking system, exploit the resonance scattering of the fish to significantly reduce ambiguities in the interpretation of the data.
