Abstract

Within the ground-penetrating radar (GPR) bandwidth a subsurface materials is considered to be an ideal dielectric, which is not always the case. We have developed the dependence of the reflection coefficient of electromagnetic waves with regard to conductivity, which showed a significant effect of the difference in conductivity on the reflectivity and signal amplitude. This was confirmed by physical modeling. The electrical conductivities of a geological media should be taken into account when solving direct and inverse problems, survey design planning, etc. Ground-penetrating radar can be used to solve the problem of mapping of the halocline or to determine water contamination.
