Abstract:

The long-term goals are to advance our understanding of the nature of high-frequency 8-50 kHz sound propagation in the ocean waveguide, with emphasis on surface, bottom, and volume effects on the forward propagated field. The central purpose of the High-Frequency Channel-Characterization Experiment HFX is to learn as much as possible about the channel impulse response or transfer function and its dynamics. Ideally, we would like to characterize the behavior as a function of 1 sourcereceiver geometry, 2 arrival angle, 3 carrier central frequency, 4 ocean volume structure, 5 bottom type, and 6 boundary dynamics, including effects of surface waves and bubbles.
