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.
