Improved efficiency of ray tracing by using adaptive step size control in anisotropic media

Abstract

Seismic ray tracing with adaptive step size control is an efficient alternative to standard ray tracing algorithms with constant step size. We present an updated version of our algorithm incorporating the Cash-Karp method and apply it in a numerical test on an inhomogeneous anisotropic velocity model. The results show that ray tracing with adaptive step size control provides higher accuracy of ray trajectories in less computation time and relieves users of the necessity to have a priori knowledge about the spatial and temporal behavior of ray propagation in a given medium.
