Abstract

Scattering of seismic waves by inhomogeneity in the earth leads to significant effects on observations of seismic energy. We apply an algorithm similar to that proposed by Beydoun and Mendes (1989) to model these scattered wavefields by combining the Born approximation and ray theory. Scattered displacements generated by a perturbation to a known background earth model are described by the Born approximation, whereby the inhomogeneity is treated as a secondary source radlating energy as it interacts with the incident waves from the true source. Variations in density act as single force sources, while perturbations to any of the 21 independent elastic constants lead to moment tensor secondary sources.
