Abstract

Forward and Adjoint Modeling Using Green’s Functions: Forward modeling of the wave equation is defined as computing the propagating wavefields for a given source-receiver distribution, the source wavelet, and a velocity-density model. This chapter presents the forward-modeling approach with the Lippmann-Schwinger (LS) equation, a summation of weighted Green’s functions over the model coordinates, in which the weights are the reflection-like coeficients in the model. Another name for this is diffraction-stack modeling under the weak scattering approximation, otherwise known as the Born approximation.
