Improving Sonar Performance Prediction Using Enhanced Environmental Knowledge
Abstract
Proposal for ONR Task Force Ocean (TFO) Improving Sonar Performance Prediction Using Enhanced Environmental Knowledge Martin Siderius, William StevensPortland State UniversityProject AbstractSonar performance prediction has been a topic of interest for decades. As currently used in Tactical Decision Aids (TDAs) the predictions are deterministic without any associated confidence. While this isadequate for some locations, it can be very misleading in others and can lead decision makers to conclude that sonar performance predictions are unreliable. A better approach is to develop a stochastic sonar prediction that includes uncertainty and provides a sense of confidence. Some areas of the globe have highly dynamic oceanography making sonar prediction much more uncertain, however, there are other areas that are much more benign and predictable. For highly dynamic areas, confidence might be low but the tactical decision should be informed by that. To tackle this long standing problem of improving sonar prediction we are taking an end-to-end approach. We are including research on acoustic propagation and ocean modeling. We are developing scenarios and metrics that are based on operations research and in consultation with the sonar community. In this way, we hope to make improvements that are achievable and practical for navy transition once the basic research has been developed. In this proposal, we are considering several areas thatwill contribute to improving sonar prediction: 1) coupling sonar prediction with the NRL Regional NCOM ocean model with ensemble estimates 2) seabed and environmental estimation using off-board sensors and through-the-sensor methods and 3) better ambient noise modeling and prediction.
