| Abstract | Traveltimes on a grid may be computed using a finite difference solution to the Eikonal equation, however that solution is based on a plane wave assumptions (Bancroft 2005a). However the wavefront may be curved and approximated by a circle. Solving for an unknown traveltime, such as a corner of the square, may involve estimating the center of the circle (center of curvature) and then computing the traveltime to the desired location. The traveltime computations assume the velocity to be locally constant within the square, but this velocity is extended outside the square to the location of the center of curvature. |
