ollecting airborne and spaceborne intelligence, surveillance, and reconnaissance (ISR) information is
mandatory for addressing the defense challenges posed
in the 21st century. A key tool for increasing the information content of ISR is using advanced electrooptical
devices, including hyperspectral imaging (HSI). This
optical sensing technology offers high spectral resolution covering visible to long-wave infrared (LWIR) wavelengths. The increase in spectral information and spectral degrees of freedom create a unique opportunity to
detect difficult targets at the subpixel level, analyze a
scene without prior information of the materials to be
encountered, distinguish hidden features and camouDigital Object Identifier 10.1109/MGRS.2019.2902525

flage, identify chemical agents in plumes, tag disturbed
earth over buried objects, and perform image classification with greatly improved accuracy. This article reviews
the military- and security-driven applications of HSI. It
analyzes and demonstrates sensing capabilities and advanced methodologies, summarizes the current spaceborne and airborne military HSI technologies, and reviews future technological developments.
PASSIVE HYPERSPECTRAL IMAGING
Modern military and defense environments require proven,
reliable, and scalable technologies for evaluating and analyzing the battle scene. Optical imaging is an integral part of
military systems because it provides solutions to the whole
defense ecosystem, including complex controls, surveillance,
intelligence, measurement, monitoring, and execution. The
