Reverberation Modeling Workshops
Abstract
Reverberation modeling is a fundamental component in numerous Navy applications including sensor performance predictions, mission planning, wargaming/campaign analysis, and most recently, synthetic sonar operator training. Because of increased interest in littoral operations, requirements for accurate system performance predictions are placing increasing demands on predictions of reverberation. Requirements for better reverberation modeling are coming from both legacy systems that employ new tactics and from new distributed autonomous systems that need deployment and control strategies. Interest in synthetic training has grown due to the increased costs of at-sea training that have resulted from limited platform availability and from restrictions imposed by marine mammal mitigation. Demands on reverberation prediction include better physics and statistical characterizations; these are required by the need to simulate bistatic and multistatic scenarios in complex (range-dependent) and variable environments using sophisticated wideband signals. Theoretical advances, the availability of high performance computers, and rapidly expanding communication bandwidths have made it technically feasible to implement many of the modeling changes necessary to meet these new requirements. The resulting recent progress in basic and applied research provides an opportunity to review current capabilities and propose improvements. These improvements, combined with operational Navy requirements, will help define new Navy Standard Models or changes to existing Navy Standard Models. Further substantiating a need, a recent report concerning verification and validation (V&V) of geoacoustic inversion techniques noted the lack of a proven method to generate synthetic reverberation data designed to test inverse techniques on reverberation data.
