High-Frequency Channel Characterization

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 this work 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) source/receiver 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. The band of interest has a variety of applications, including mine countermeasures, tracking odontocetes in navy ranges, and bottom mapping; however, the core interest in this program is for acoustic communications.
