Resolution of initial field of rough surface PE based on semi-space green´s function

This study presents a new method to introduce the effects of rough surface when the initial field of parabolic equation model is solved. It was characterized by rough surface reflection coefficient from the well known Miller-Brown model and included in the transforming course from non-boundary space to semi-space. The whole procedure of solving initial field for parabolic equation model was build up. Numerical experiments of two typical cases were performed. Numerical results enable the proposed method to be checked and present a straightforward understanding of the new method.
