Experimental data of a directional borehole radar system for UXO detection

Ground penetrating radar (GPR) is a well-known method for exploring the subsurface. Typically, the antenna system is located at the surface. This approach is not feasible if the target of interest is beyond the detection range of this surface equipment, for example because this target is located too far away or behind a highly conductive barrier. Directional borehole radar is an effective method in these cases. In this paper, we present experimental data of a directional borehole radar for UXO detection. We describe the operation and results of an impulse directional borehole radar that was developed for UXO detection. Both laboratory and field data are shown and the types of processing that we apply on them. We will also describe some differences and similarities with impulse surface radar.
