Abstract

Summary

Ground-penetrating radar (GPR) is a non-destructive geophysical technique that uses electromagnetic (EM) waves to image the near surface. It is widely used for solving geological, geotechnical, archeological, or civil engineering problems. The popularity of the method is thanks to its speed, effectiveness, relatively low cost and reliability. However, GPR has some limitations as well. The main reason is the strong attenuation of GPR waves in the conductive material. For example, the method rarely can be applied successfully in low resistivity environment (e.g. in the presence of clayey wet soils). Resolution and penetration depth are also limited. That is why measurement design must be the first step in the beginning of a GPR project. Forward modeling can be also useful before the on-field GPR survey, especially if there are available information about the area.
