Mid-Frequency Reverberation Measurements with Full Companion Environmental Support

Abstract

The goal of this project was to measure mid-frequency (1-10 kHz) shallow water reverberation with full companion environmental measurements so that model/data can be compared without ambiguity. Included in the goal was to make statistical estimates of the uncertainties associated with all the environmental conditions. A key element was to understand the mechanisms that cause clutter, approaching the subject by emphasizing contemporaneous environmental and acoustics studies in order to quantitatively understand dominant physical mechanisms. The major components of the research are transmission loss, bottom and sub-bottom impact on propagation and scattering, surface and water column influence on propagation, culminating in a full understanding of the physics of shallow water mid-frequency reverberation. The experiment was conducted off Panama City, Florida, at nominally at 20m water depth to reduce the burden of making environmental measurements.
