Hyperspectral MWIR infrared imagers are required to characterize signatures of military targets, both cooperative and hostile. The specific need is the characterization of missile plume and hardbody signatures in static and free flight tests. This threat characterization supports the design and testing of missile warning and countermeasure systems. The hyperspectral imagery data would also be useful in temperature/emissivity determination of hypersonic thermal protection systems during ground tests in arc-heated facilities.The focal plane of the imager should consist of at least 100 x 100 spatial pixels (threshold) with an objective of 256 x 256 spatial pixels or greater. Full-frame hyperspectral cube data rate should be at least 60 cubes per second (threshold) with an objective of 120 cubes per second or faster. The spectral resolution should be 40 nm (threshold) with an objective of 30 nm or better. The detector pixel pitch should be no bigger than 30 mm, with an objective of 15 mm. The detector well depth should be at least 30 Me-. The field of view of the hyperspectral imager shall be adjustable through the use of optics/lenses that do not impact the basic functionality. Snapshot data acquisition is preferred over scanning mode.
