A new tool for the retrieval of effective permittivity of ground by using a commercial GPR

Abstract

We propose a fast and effective method for estimating the dielectric permittivity of pavement materials. The method is based on a transmission-line analytical model of the ground and on the use of a commercial ground penetrating radar (GPR) system. In order to verify its reliability and effectiveness, we apply the method for retrieving material permittivity of an actual airport taxiway pavement. We estimate the permittivity comparing the measured GPR received signal and the analytical one. The correct permittivity values are found by imposing the maximum correlation between the measured GPR signal and the analytical one.
