AbstractA 3D FDTD simulation of ground penetrating radar (GPR) is described. The soil material is characterized by inhomogeneities, conductive loss and strong dispersion. The dispersion is modelled by a N-th order Lorentz model and implemented by recursive convolution. The perfectly matched layer (PML) Is used as an absorbing boundary condition (ABC). This formulation facilitates the parallelization of the code. A code is written for a 32 processor system. Almost linear speedup is observed. Results include the radargrams of buried objects.
