Recent peacekeeping missions by Canadian Forces in Somalia and the former Yugoslavia have highlighted deficiencies in current land mine detection capabilities. In response, the Improved Land Mine Detection Project (ILDP) was initiated by the Canadian Department of National Defence (DND) in 1994 to develop and test a remote controlled, vehicle-mounted mine detection system employing multiple ;sensors and real-time data fusion technology. In addition to pulsed induction electromagnetic (EM), infrared (IR) and thermal neutron activation (TNA), the primary sensor suite includes a commercially developed ultra wideband ground penetrating radar (GPR). In principle, by sensing the dielectric contrast between mines and the soil matrix, GPR is capable of detecting non-metallic as well as metallic landmines. However, preliminary testing of the GPR at Defense Research Establishment Suffield (DRES) has established that GPR detection performance is strongly influenced by space and time-variable soil conditions. As requested, Golder Associates has undertaken a combined laboratory-field investigation of DRES mine-lane soils to characterize both spatial variability in electrical properties along the test lane and time-dependent fluctuation related to environmental variables, including precipitation and temperature.
