FMCW GPR radar for archaeological applications: First analytical and measurement results

This paper describes a Ground Penetrating Radar (GPR) using frequency modulated continuous wave (FMCW) technique which produces 2D images for archeological detection. This radar operates at 745 MHz, with a bandwidth of 510 MHz. For a first evaluation of the GPR system, a structure was set up to emulate the flight of an Unmanned Aerial Vehicle (UAV). The radar is capable of acquiring and storing data in order to do a post-processing using range migration algorithm (RMA). The results are evaluated by imaging a metal plate of 50 cm of diameter with a burial depth of 0.3 meters.
