Synthetic seismograms from extended ray tracing

Andrzej J. Hanyga, Hans B. Helle

Abstract

In [1,2,3] a method of numerical computation of wave fields is developed. It is an extension of Asymptotic Ray Theory (ART) applicable in regions containing caustics. The essential features of the new method. called Extended Ray Tracing (ERT), consist in application of expressions which are well-defined at caustics in combination with complex ray tracing in caustic shadows.
