Paper Abstract

We introduce a theoretical model describing wave propagation in layered media. This theory relates medium properties (i.e. P- and S-wave velocities and density) to travel time delay and pulse attenuation. Approximation schemes are based on the assumption that the change of medium parameters is not large. If changes are large, then higher order approximations can be obtained by successive iterations. Several numerical examples show the effects of target-zone scattering. The main purpose of this work is to provide an accurate understanding of seismic amplitudes in realistic geological models. It is hoped that these results will lead to more robust seismic inversion analysis.
