Abstract

The CARPE3D model significantly enhances the capability of three-dimensional parabolic equation propagation models to simulate complex marine environments, serving as a high-precision tool for three-dimensional ocean acoustic propagation. Despite its advanced performance, the model still has certain limitations. To address these issues, this paper proposes improvements to the classic CARPE3D model by utilizing higher-order three-dimensional parabolic equations and the split-step Fourier method for acoustic field calculations. The accuracy and precision of the improved model are validated through simulation and error analysis.
