Abstract

P278 Acoustic Time-Domain Inversion of Focussed Data C.H. Lam* (Delft University of Technology) P.M. van den Berg (Delft University of Technology) & A. Gisolf (Delft University of Technology) SUMMARY A local inversion method based on the Born/WKBJ approximation is presented. Inhomogeneous smoothly varying background models are used. Previously the application of the WKBJ-approximation for the Green’s function in forward scattering problems was shown to be superior to the use of the standard homogeneous Green’s function for a large class of seismic problems. This result encourages the use of smoothly varying background models in inverse modeling of which first step inversion
