Abstract
A Naval Infrared Search and Track (IRST) demonstrator has been developed for the UK Ministry of Defence. The system uses two staring infrared cameras and split field of view optics to provide panoramic surveillance of the horizon. Use of staring detectors provides improved sensitivity and faster update rate than current scanning IRST systems. The demonstrator is fitted with commercial 640x512 pixel medium waveband detectors but is designed to accommodate 1024x768 pixel detectors in the future. The system features switchable spectral filters to allow choice of the optimum waveband for the prevailing environmental conditions and beam steering optics for non uniformity correction and image stabilisation. Real time processing has been implemented using a combination of Field Programmable Gate Array and PowerPC hardware for detection and tracking. The paper describes the system and presents some examples of its output.
