Abstract
The feasibility of using off-the-shelf broadband thermal infrared (TIR) cameras, (3-5 micron and 8-12 micron) for the aerial detection of unexploded explosive ordnance (UXO) was investigated in support to the Canada Department of National Defence UXO Legacy Site Program. UXO represent environmental, health and safety hazards in many parts of the world. Ground and aerial surveys are typically the first step in the removal process, and can involve visual detection from people walking on the ground, ground-based sensors such as ground penetrating radar (Andrews et al., 1999; Arcone et al., 2000) and electromagnetic sensors (Zang et al., 2003; O’Neill et al., 2005) and/or airborne sensors such as ultra-wideband synthetic aperture radar (Sullivan A., 2002; Sullivan et al., 2000). No single sensor can detect UXO in all possible conditions (buried, covered, wet, under water) with a zero false alarm rate. It is instead a combination of different sensors that provides the best approach (Shamatava et al., 2004; Marble et al., 2000). The Nicolet firing range on the shore of Lac Saint-Pierre was selected for the experiments because of its well-known UXO problem. Moreover, because the lake water level fluctuates and vegetation quickly grows over barren soil after water retreats, surveys of the area are incomplete. Airborne detection could aid in solving this problem. In order to understand the thermal UXO/background behavior and determine the best image acquisition parameters (time of d
