The Study of GPR with Conducting Surfaces to Determine the Operating Frequency in Single-Fold Reflection Profiling

Abstract

Mapping of different soil surfaces is possible by the means of ground penetrating radar (GPR). To optimise the interpretation of such radar surveys carried out at various sites, we turned our attention to the accuracy of GPR on different geophysical surfaces. The properties of soil significantly influence the GPR performance, modifying, in particular, the propagation velocity, skin depth, phase constant and attenuation. Thus, setting the parameters for a GPR survey is not easy. Also, it is difficult to decide the right operating frequency for GPR operations. In order to get a higher penetration depth, the user will have to compromise with the resolution of the GPR or vice versa. Here, we try to estimate an appropriate operating frequency for GPR survey, if the properties of the soil are known.
