Paper Abstract

We present a numerical method of computing asymptotic Green's functions for applications in linear inversion of seismic reflection data. The method is based on tracing a density sampled ray field, which is locally interpolated for ray field parameters. We propose a uniformly valid asymptotic formula relating the wave field to the ray field parameters. A few test bases and an application to the linearized inversion of seismic reflection data are presented.
