f 3D Numerical modelling of GPR including polarization effects - The TLM method

The application of Ground Probing Radar (G.P.R.) in the exploration for buried antiquities is growing rapidly. Its high resolution and non-destructive nature are G.P.R.'s principal advantages over other well established geophysical methods such as resistivity and magnetometery which are routinely applied today at archaeological sites. However, interpretation of the G.P.R . data is not always a simple procedure, especially when the targets sought are not of a simple geometry as usually are the archaeological ones. Therefore, to facilitate interpretation and also to get an insight the G.P.R.'s detection mechanism a 3D numerical model was developed.
