Acoustic Resonance Classification of Swimbladder-Bearing Fish at Multiple Scales

Abstract

Long-term Goals: To accurately describe the spatial and temporal distributions of fish and to quantify the mid-frequency clutter characteristics of fish. Objectives: 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 long-range horizontal-looking and short-range downward-looking systems, exploit the resonance scattering of the fish to significantly reduce ambiguities in interpretation of echo data.
