Tomographic full waveform inversion and linear modeling of multiple scattering |

where:

is the velocity vector, is a wave-equation operator non linear with respect to velocity perturbations and the data vector is the pressure field measured at the surface.

The wave-equation operator is evaluated by recursively solving the following finite difference equation

where is a finite-difference representation of the second derivative in time, is a finite-difference representation of the Laplacian, and is the source function.
