Abstract :
We propose a unified full-waveform method for modeling zero-offset, off-ground ground penetrating radar (GPR) and electromagnetic induction (EMI) in multilayered media. Both GPR and EMI systems are set up using vector network analyzer technology. The antennas are modeled using frequency dependent, complex transfer functions, which include interactions with the medium layers. Wave propagation and induction effects are accounted for by means of three-dimensional (3-D) Green´s functions. Laboratory results demonstrated the high accuracy of the GPR and EMI models. This shows great promise for non-destructive characterization of soil and materials.
