Uncertainty DRI Adaptive Rapid Environmental Assessment

The objective of the AREA research is to develop a probabilistic methodology for optimal, in-situ assessment of the environmental parameters most critical to the uncertainty of the acoustic prediction, within constraints of the actual acoustic system configuration and the available tactical REA resources. The goal is an efficient modeling and simulation framework, which allows for real-time prediction of the reduction in sonar performance uncertainty associated with specific deployment strategies for the REA resources. Specific scientific objectives include a fundamental understanding of the relative significance of individual environmental parameters to performance of a specific sonar system and based on this understanding defining optimal parameterizations of the environmental parameters. Another crucial component is the classification of the limiting spatial and temporal scales, below which the in-situ sampling resources are totally inadequate and the uncertainty remains stochastic.
