Abstract

Electromagnetic and elastodynamic scattering and inverse scattering techniques are combined to provide a better understanding of wave propagation and obstacle imaging in concrete. In particular we propose an electromagnetic inversion algorithm for ground probing radar data to include information about the dipole moment of the antenna; a new elastodynamic inversion scheme is even capable of processing the complete pressure and shear wave information as contained in the components of the displacement vector simultaneously, where we compute the necessary synthetic data with the numerical EFIT code (Elastodynamic Finite Integration Technique) as extended to statistically inhomogeneous media in order to validate the inversion algorithm.
