Multispectral data in the mid-wave spectral region can provide significant information for the characterization of both manmade objects and natural background. Processing multi-spectral images is still in its infancy, complicated by the fact that spectral characteristics change from place to place in the scene. A multispectral high performance imaging sensor for the spectral region 1.5 - 5.2 µm has been specified and obtained from AEG INFRAROT-MODULE GmbH. The instrument is equipped with a spinning filter wheel containing four filters closely related to the atmospheric windows. The spectral bands are also selected to distinguish between reflected and emitted radiation and also to distinguish between targets of different temperature and emissivity. The full frame rate is 100 Hz, and up to 800 Hz is possible using sub-windowing. Applications include missile warning, reconnaissance, surveillance, tracking and identification.
