Paper Abstract

The Multiband Electro-Optical Scanner is an experimental laboratory demonstrator, the purpose of which is to investigate the feasibility of missile detection using a scanning thermal imager in a number of discrete wavebands. The demonstrator utilizes three mid-IR wavebands and one FIR waveband to discriminate spectrally between real targets and false background clutter. The narrow instantaneous fields of view of these four detectors are scanned using broadband reflective optics common to all four beams, to provide a field of 3.5 x 10 deg. The signals from two reference blackbody sources are injected once per frame to provide radiometric calibration. The system design is described, illustrating the impact of optomechanical design on systems considerations.
