Development of Mid-Frequency Multibeam Sonar for Fisheries Applications

Abstract

The long-term goal of this program is to investigate the utility of mid-frequency (approx. 1O kHz) acoustics to detect, enmuerate, and identify pelagic fish distributions. Objectives of this research include: comparisons of fish backscatter models, models of mid frequency sound propagation, development of a mid-frequency multibeam sonar, and backscatter measurements using splitbeam echosounders and the multibeam sonar.
