LONG-TERM GOALS The overall long-term goal for this project is to enhance the Navys 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 projects 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.
