| Abstract: | The authors present a refraction forward modelling algorithm in the paper. It is based on the discrete plotting of a model and the ray path searching and uses the Fermat theory as criterion. It fits with a model with any fluctuation of refractor and surface. The refraction velocity can vary in the horizontal direction. The algorithm runs fast and is very effective. It is of great importance to the research into the refraction static effects in the desert and mountain areas. |
