The Andersson et al. survey found that “households with a mine ______________ 1 Estimates of the total number of landmines, the number of victims, and the mine clearance rates are highly uncertain because only about 30 countries have conducted formal surveys (ICBL, 2001). S. State Department surveys. The estimates of the number of victims are from the International Campaign to Ban Landmines, which annually documents landmine injury data.
1—Images of Landmines Produced by GPR System cal in the design of a GPR system are signal-processing algorithms, which filter out clutter signals and select objects to be declared as mines. GPR is a mature technology, but it has not yet been widely deployed for mine detection. GPR was first used in 1929 to measure the depth of an Austrian glacier (Olhoeft, 2002). The Army tested rudimentary GPR techniques for mine detection in the 1940s. The first commercial GPR systems were developed in 1972. Since then, use of GPR for locating buried objects ranging from utility pipelines to archaeological artifacts has proliferated.

INNOVATIVE ELECTROMAGNETIC DETECTION SYSTEMS A number of innovative methods are being explored that search for buried mines based on changes in the electromagnetic properties of the surface soil and shallow subsurface. These methods include ground-penetrating radar (GPR), electrical impedance tomography (EIT), x-ray backscatter, and infrared/hyperspectral systems.
