Imaging the soil physical parameters with surface seismic recordings is a non linear inverse problem. The elastic full waveform inversion is a quantitative multiparameters imaging method of diffractors that requires beforehand the knowledge of an initial velocity model. <br /><br />The corresponding forward problem, the elastic waves propagation, is solved in the frequency domain, allowing to efficiently take into account multisources and multireceivers acquisitions, with a finite difference method that modelizes the propagation of all wave types (body waves, surface waves, diffrated waves, refracted waves ...). The chosen finite difference stencil precisely simulates the free surface and surface waves propagation. <br /><br />This lineariz...
