Quantitative GPR inspection of quasi-homogeneous ground layers

Abstract

This work covers methods of GPR monitoring of constructions that are quasi-homogeneous ground layers. The monitoring methods include the determination of complex dielectric permittivity and moisture of the construction layers of highways and railways. In order to obtain quantitative values of these parameters the GPR method is calibrated via the measurement of these quantities using the resonance method at frequencies close to the central frequency of the microwave radiation used.
