2D computations of 3D synthetic seismograms using the ray-based Born approximation in heterogenous model P1

Libor Sachl


The accuracy of the ray-based Born approximation of the first order is tested in a smooth 2D heterogenous background model P1. Only P waves are considered. 3D synthetic seismograms are numerically calculated by the Born approximation in a 2D grid and are compared with the ray-theory seismograms. The born seismograms contain reflected and diffracted waves. Individual reflected and diffracted waves are identified.
