Abstract
This paper deals with the regularization problem raised by the inversion of GPR radargram. The determination of subsurface conductivity and permittivity profiles leads to Laplace transform inversions for real data. A very recent method to solve this severely ill-posed problem is presented and evaluated using a standard 2D FDTD numerical GPR model for multilayered media.
