Generation of Synthetic SAS Data for Targets Near the Seafloor: Propagation Component

Abstract

Award Number: N00014-10-1-0114 http://www.apl.washington.edu/projects/projects.php/ Overview:This report contains three parts. First, a list of archival journal publications, conference proceedings, and abstracts for oral presentations are listed. It is noted that the research reported in these papers and presentations was performed in conjunction with "Generation of Synthetic SAS Data for Targets near the Seafloor: Propagation Component," (ONR Award N00014-07-G-0557/0023). Second, the fast ray model for target scattering in a homogeneous waveguide has yet to be published in an archival journal, but an overview has been given in the conference proceedings for the First International Conference and Exhibition on Underwater Acoustics, Corfu, Greece. As this proceedings paper is currently only available from the conference website and its availability may not be ensured, the paper is included in this final report. Finally, recent benchmark model comparisons of the fast ray model and a wave propagation model, based on the trapped modes in propagation in a homogeneous Pekeris waveguide, revealed an significant deficiency in the implementation of fast ray model. The details of the deficiency and the correction to the implementation of the fast ray model are given in a section that follows the proceedings paper.
