The long-term goal is to accurately describe the spatial and temporal distributions of fish and quantify the mid-frequency clutter characteristics of fish. The objective is to conduct a new class of quantitative studies of acoustic 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 short-range downward-looking system, exploit the resonance scattering of the fish to significantly reduce ambiguities in the interpretation of the data.
