Acoustics in Uncertain Ocean Environments
Abstract
In the last two decades, sophisticated computational routines for underwater acoustics have been developed, and advances in computational power have put real time use of these routines in reach for sonar applications. However, the US Navy must often operate in unfamiliar waters where the basic environmental inputs to the computational routines may be uncertain or unknown. In this situation, the value of computations must be assessed because uncertainty in environmental parameters will translate into uncertainty in the acoustic field predictions. The long term goals of this project are: i) to quantitatively determine the uncertainties in underwater sound field predictions that arise from uncertainty in environmental parameters, and ii) to determine how to exploit in-situ acoustic measurements and the generic propagation characteristics of underwater sound channels in order to enhance the performance of active and passive sonar systems in unknown or uncertain ocean environments.
