Efficient Acoustic Uncertainty Estimation for Transmission Loss Calculations
Abstract
The overall long-term goal for this project is to enhance the Navy's predictive capabilities in uncertain ocean environments. This project is a collaboration with Dr. Robert Zingarelli at the Naval Research Laboratory - Stennis Space Center (NRL-SSC). At the time of this project's proposal, the long-term goal was the integration of the existing field-shifting algorithm [1,2] with uBand. However, for the uncertain variables of greatest interest to NRL-SSC, alternative reciprocity-based or calculation-statistics- based techniques are likely to provide more accurate results with greater computational efficiently than the field-shifting approach. At present, the long-term goal for this project is to produce techniques and algorithms that improve the performance of uBand for predicting TL uncertainty in underwater environments of interest to the US Navy. The specific objectives of this project are: a) fully explore the applicability and utility of the reciprocity and calculation-statistics approaches for TL uncertainty estimation for uncertain source depth throughout the parameter ranges of interest, b) integrate the better of these two techniques into the existing uBand algorithm, c) develop other techniques (possibly including FS) for uncertain variables or environments where uBand performs sub-optimally.
