Efficient characterization of military target infrared (IR) signature plays an important role in any countermeasure defense program for the design of unmanned monitoring systems capable of ranging and tracking different targets as well as performing automatic detection and recognition of potential threats. In order to do so, large IR signature databases are built upon testing of multiple targets such as camouflage materials under various backgrounds conditions, at multiple wavelengths, and using different sensor technologies.
