STRONGLY NON-LINEAR INVERSE SCATTERING FOR ELASTIC PARAMETERS IN HALF-SPACE

The inversion of strong scatterer imbedded in the half-space is a practical, but very difficult problem of strong non-linearity. The Born iterative method is only suitable to weakly non-linear problems. Based on DBI(distorted Born iterative) method, an iteration algorithm is proposed for solving this kind of strongly nonlinear problems. In the numerical simulation process the moment method is employed for discretization and the resulting ill-conditioned matrix equation is solved through the regularization technique. The numerical results show that this approach can converge fast and achieve a high accuracy.
