A Horizontal Spatial Requirement Study of the Gulf Stream as Modelled by the IFDPE (Implicit Finite Difference Parabolic Equation) Acoustic Model.

Abstract

The sampling increment in horizontal spacing for a range-dependent environment was studied with respect to accurate prediction of propagation loss through a frontal system. A transmission loss model was verified by comparing its predictions with experimental data when the sampling increment was very small. A study of the effect of altering the sampling increment produced a maximum increment which retained a reasonable agreement with the prediction for very small incrementation. Sensitivity studies were performed at three source depths to determine depth dependency.
