Surface Forward-Scattered Acoustic Measurements and Analysis

Abstract

A shallow water, high-frequency acoustic experiment was conducted off the coast of Panama City Florida during August 1991. Acoustic measurements of surface forward scattering, surface reverberation, and direct path intensities were made utilizing two (2) large stationary towers resting on the seafloor. Each tower was equipped with horizontal and vertical receiving arrays, while the two (2) sources were located on only one of the towers. The water bottom was 30 m deep and covered with a fine, rippled sand. The range of acoustic frequencies varied from 20 kHz to l8O kHz. Concurrent environmental measurements including wave heights, sound velocity profiles, and sample cores were made. This paper reports on the surface forward-scattered measurements made at 24 kHz.
