Comparative study using an UWB measurement system and a RAMAC GPR system for subsurface imaging of the vaucluse karst aquifer

The use of Ground Penetrating Radar is ubiquitous in near surface geophysics for subsurface object detection with a growing interest for hydrogeology monitoring and rock fracturing purposes. Conventional GPR surveys are done using narrow-band omnidirectional antennas. In this paper, we present a comparative study using an ultra-wide band measurement system and a RAMAC Ground Penetrating radar for subsurface imaging devoted to the survey of the karst aquifer located in the Vaucluse in Provence (French ANR MAXWELL Research Project).
