Analysis of Spatiotemporal Clutter Statistics and Support for the Five Octave Research Array

Abstract

Chief goals and accomplishments of this project are summarized in the attached final report. Publications (3), a report for the major experimental endeavor (the seabed characterization experiment of 2017, deemed SCEX17), and documentation for the final acceptance of the new Ocean Acoustics towed line array are also attached with the report. Significant scientific work included advancements in characterizing and modeling spatial coherence statistics for active littoral sonar reverberation, and an SCEX17 geoacoustic inversion analysis finding significant evidence of a low sound speed seabed within the SCEX17 experimental region. During the SCEX17 experiment, PSU-ARL collected close to a terabyte of acoustic data, primarily in the interest of geoacoutics inversion and seabed scattering research. Finally, a significant amount of effort went towards a trade study of the best way to move forward with the aging FORA array, and management of design and development of a FORA replacement ONR-OA towed line array acquisition system.
