Two-dimensional multivalued traveltime and amplitude maps by uniform sampling of a ray field
An algorithm for computing multivalued maps for traveltime, amplitude or any other ray-related variable is presented. It is based on a wavefront construction method, where the ray field is decomposed into elementary cells defined by adjacent rays and wavefronts. A sampling criterion for ray density...

Summary: | An algorithm for computing multivalued maps for traveltime, amplitude or any other ray-related variable is presented. It is based on a wavefront construction method, where the ray field is decomposed into elementary cells defined by adjacent rays and wavefronts. A sampling criterion for ray density in the phase space is suggested. It is demonstrated that this new criterion ensures uniform ray density over the entire ray field including caustics. the method is applied to complex models. |
