Abstract
Summary
We derived the Nonlinear sensitivity operator in nonlinear tomographic waveform inversion based on the theory of nonlinear partial derivative operator. We apply the renormalization procedure (De Wolf approximation) to the forward and inverse T-matrix series. Numerical tests proved that the renormalized inverse scattering series has much better convergence property than the inverse Born series. This convergence improvement may be applied to the iterative procedure of waveform inversion.
