Abstract
At the TNO Physics and Electronics Laboratory (TNO-FEL), one of the recent research programs explores the use of ultra-wide-band (UWB) electro-magnetic fields in a bi-static ground-penetrating radar (GPR) system for the detection, location and identification of buried items of unexploded ordnance (e.g., land mines). An experimental UWB ground-penetrating radar system was designed to operate in the frequency band from 200 MHz to 3 GHz and uses impulse radiating antennas (IRAs) as transponders to radiate and receive very short electro-magnetic pulses from a short distance above the soil. Part of the development of this UWB GPR system involved the erection of an outdoor tent covered UWB GPR testing facility. In another program an outdoor multi-sensor humanitarian de-mining test facility was constructed. This facility enables semi-automated measurements, with several different sensor on lanes with different soil types. This article highlights the development of the above mentioned system and facilities and presents some results obtained with one of the commercial systems that is present at the site.
