Efficient Acoustic Uncertainty Estimation for Transmission Loss Calculations

Abstract

LONG-TERM GOALS: 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). The primary focus of this project is enhancing the accuracy and utility of the existing uncertainty band algorithm (uBand) for predicting transmission loss uncertainty in a wide variety of ocean environments. A long-term goal at the time of this project's proposal was the integration of the existing Field-Shifting algorithm (FS) with uBand. For the uncertain variables of greatest interest to NRL-SSC, however, a new reciprocity-based technique provides more accurate and efficient results than FS. At present, the long term goals for this project are: a) fully explore the applicability and utility of the reciprocity algorithm in transmission loss uncertainty estimation, b) integrate the reciprocity technique into the existing uBand algorithm, c) develop other techniques (possibly including FS) for uncertain variables or environments where the current version of uBand and the reciprocity approach perform suboptimally.
