Paper Abstract

Land mines, and other buried explosive devices, are widely deployed all over the world. As such, they pose a significant threat to dismounted soldiers, vehicles, and civilians. Land mines inhibit the safe movement of troops and produce chaos in countries struggling for socio-economic stability long after the cessation of hostilities. Consequently, there has been much investigation into how buried explosives might be detected and safely neutralized. Many different electro-optical and radar sensor systems have been considered for the detection of buried land mines. These include ground penetrating radars, polarization detectors, and visible/thermal infrared (IR) imagers. This paper will describe the efforts to develop a near IR/LWIR mine detection system. The core of the discussion will include highlights of a two-color LWIR QWIP sensor system designed to provide uniform, high spatial resolution, multi-color co-registered imagery and possess negligible spectral cross-talk. The current developments have been sponsored by the Defense Advanced Research Projects Agency (DARPA) for developing a visible/infrared mine detection system, which when deployed on a TUAV would increase the war fighting effectiveness of any rapid deployment force by facilitating ground penetration into hostile territory.
