Application of electromagnetic field modelling in GPR investigations of an historic tenement

The article presents the results of Ground Penetrating Radar (GPR) measurements carried out in a historic tenement in Krakow. The aim of this study was to check if there is a basement under the apartment's floor. In order to verify the results, modelling attempt of electromagnetic field evolution in the medium was undertaken. The numerical simulation of GPR impulse passage in the medium uses the finite-difference time-domain method (FDTD). Synthetic radargrams obtained as a result of the modelling were compared with measurements processed radargrams.
