Hyperspectral data were collected for different explosions during the Northern Lights I (2002) and II (2005) trials at DRDC Suffield with the PIRATES imaging system. The AIRIS imaging system measured explosions only in 2005. In this study, intensity-time curves were processed for each event regardless of the atmospheric transmittance. The curves were evaluated for bands 2.04 to 5.26 µm for AIRIS and PIRATES and for each LEGACY band. Transmittance-corrected intensity- time curves for LEGACY bands were analyzed to identify which bands were the best to discriminate the explosion elements (charge, composition, container shape, and container material). Bands S4 and S5 for the short wave infrared detector and bands M4, M5, and M6 for the medium wave infrared detector were the best options to discriminate explosions according to all events. The bands S7 and M4 were considered the best only when AIRIS measurements were considered. The difference between results of both imaging systems is probably due to their different altitude and angle of observation. The conclusions agree with the use of the bands S4, S7, and M5 by LEGACY during the Northern Lights II trial. This work was conducted in the framework of Public Works and Government Services Canada contract number W7701-092854/001/QCL on behalf of Defence Research and Development Canada –Valcartier. This work was also done in support of a classified project.
