Abstract

This method of solving the parabolic equation of propagation over the sea has proved the most popular on account of its performance in terms of computation time, and is equally well adapted to analysis in the presence of atmospheric ducts. The authors present an analysis of the method starting from the parabolic equation. They then show their implementation of the Fourier split-step algorithm as well as the boundary conditions necessary for its application. The algorithm is applied to the study of wave propagation over a sea surface. The results of calculation are presented for an atmosphere and a sea state often occurring in coastal regions
