Traveltime-Based True-Amplitude Migration in Anisotropic Media

P286 Traveltime-Based True-Amplitude Migration in Anisotropic Media C. Vanelle* (University of Hamburg) & D. Gajewski (University of Hamburg) SUMMARY True-amplitude Kirchhoff migration is a task of high computational effort. A substantial part of this effort is spent on the calculation of Greens functions (GFTs) i.e.~traveltime tables and amplitude-preserving weight functions. So far dynamic ray tracing (DRT) had to be applied to generate the GFTs. However DRT is an expensive and complicated task if anisotropy has to be considered. Also storing the GFTs leads to large demands in computer storage in addition to the high requirements in CPU time. In this
