Abstract
Transmission losses measured in a range-dependent ocean environment are compared to two-way parabolic equation (PE) predictions. The field experiment employed SUS charges as the acoustic sources and a towed line array as the receiver in a region where the bottom shoals almost uniformly from 1500 to 500 m along a 14.6-km track. Simulations of upslope propagation indicate that two-way PE codes are more accurate than one-way PE codes. In addition, the two-way PE implementation has the capability of modelling backscatter.
