Fundamentals Of Ground Penetrating Radar

Ground penetrating radar (GPR) is a relatively new technique for<br>investigating shallow geologic, engineering and hydrologic features. The principles<br>and theory are based on the wave equation derived from Maxwell’s Equations for<br>electromagnetic wave propagation, and the antenna designs have evolved from field<br>testing. GPR data is presented in the form of time-distance plots that are analogous<br>to conventional seismic records. This paper presents an overview of: 1) the<br>theoretical basis for GPR, 2) guidelines for GPR interpretation, and 3) practical<br>field examples of GPR data.
