Abstract
The emergence of new infrared camouflage and countermeasure technologies in the context of military operations has paved the way to enhanced detection capabilities. Camouflage devices such as candles (or smoke bombs) and flares are developed to generate either large area or localized screens with very high absorption in the infrared. Similarly, soldier's camouflage devices such as clothing have evolved in design to dissolve their infrared characteristics with that of the background. In all cases, the analysis of the targets infrared images needs to be conducted in both multispectral and hyperspectral domains to assess their capability to efficiently provide visible and infrared camouflage. The Military University of Technology has conducted several intensive field campaigns where various types of smoke candles and camouflage uniforms were deployed in different conditions and were measured both in the multispectral and hyperspectral domains. Cooled broadband infrared cameras were used for the multispectral analysis whereas the high spectral, spatial and temporal resolution acquisition of these thermodynamic events was recorded with the Telops Hyper-Cam sensor. This paper presents the test campaign concept and the analysis of the recorded measurements.
