Rough Surface Models Implemented Within the Split-Step Parabolic Equation Algorithm
Abstract
Three split-step PE rough surface models-mixed transform (MT), surface loss function (SLF), and approximate solution (AS)-were investigated and compared with a reference waveguide model called MLAYER. The MT and SLF models are shown to agree well with MLAYER; the AS model, however, generally showed poor agreement. The ML model, though the most accurate, is the most time- consuming of the three. The AS model, the most numerically efficient, shows the poorest match to MLAYER. In using one of these rough surface models, whether it be to model rough surface effects over ocean or variable terrain, a satisfactory compromise may be to use some form of the SLF model since it is shown to agree fairly well with MLAYER and is still fairly efficient.
