WebJul 1, 1993 · Dynamic ray tracing (DRT) is important in evaluating high-frequency seismic wave fields in complicated structures. Two formulations of the DRT equations for inhomogeneous anisotropic media are presented. One of them is represented by the classical DRT system, suggested by Cerveny 15 years ago. Both systems are specified in … WebLet's look at some examples of multiple reflection events in seismic data. We review what the multiple is and show some examples of waterbottom and interbed ...

WebNew methods for the fast, accurate and efficient calculation of large classes of seismic rays joining two points x S and x R in very general two-dimensional configurations are presented. The medium is piecewise homogeneous with arbitrary interfaces separating regions of different elastic properties (i.e., differing wave speeds c P and c S ). WebA new approximate algorithm for two-point ray tracing is proposed and tested in a variety of laterally heterogeneous velocity models. An initial path estimate is perturbed using a geometric interpretation of the ray equations, and the travel time along the path is minimized in a piecewise fashion.

WebFundamentals of Ray Tracing Rick Aster March 28, 2011 A key observation that we can make about a seismic signal is its arrival time.
