Mid-Frequency Reverberation Measurements with Full Companion Environmental Support
Abstract
The long-term goal is to understand mid-frequency (1-10 kHz) acoustics in shallow waters through measurements and modeling, including propagation, reflection, and forward- and backscatter, as well as reverberation. The top-level goals of this effort are to understand the important environmental processes that impact mid-frequency sonar performance in shallow water environments, and to develop means to efficiently collect those environmental data. The overall goal is to conduct a reverberation measurement in very shallow water off the coast of Panama City, Florida in FY13. This field project is part of TREX (Target and REverberationeXperiment). The frequency range is 1-10 kHz, emphasizing 3-4 kHz. The Navy relevance is reflected in the fact that detection using mid-frequency sonar is in most cases reverberation limited. The proposed work addresses a clear need in basic research for a 6.1 level measurement program,using well-controlled geometries and high resolution environmental measurements, designed to test models predicting reverberation and also to quantify the most important environmental measurements to make in order to maintain accuracy in those predictions. Data from such an experiment can be used for testing various forward and inversion techniques, and can also be used for training purposes.
