Improved Approach for Modeling Acoustic Fluctuations.
Abstract
The Navy relies on sonar-system performance predictions for many applications -- from concept and design through direct Fleet tactical aids. Each application involves a specific amount of ensembling over conditions and requires a certain level of accuracy. Performance predictions are usually generated through detection or tracking simulations, employing computer models for engagements between targets and sensors. Whether a Monte Carlo or analytic approach is used, the statistical results depend principally on the scenario, the system response and the acoustic environment. This study concentrates on the last item, the environmental acoustic (EVA) parameters and their fluctuations, and how it impacts performance-prediction capability.
