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, the Navy's transmission loss (TL) uncertainty prediction program. 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, specifically when the source depth is uncertain.
