Abstract : This report summarizes the present status of the development work at the Diamond Ordnance Fuze Laboratories on a passive infrared fuzing system for use against airborne targets. The target signal used is the infrared radiation from the hot water vapor in the jet exhaust plume. The fuze detection system operates in the 2.7 micron region and consists of a dual optical system which utilizes arsenic trisulfide lenses and lead sulfide photoconductive cells. Flyover measurements of jet aircraft indicate that this fuze will receive target signals on the order of 50 mv at a miss distance of 50 ft. This system is not only immune to radio countermeasures, but, because of range cut-off, should be relatively immune to infrared countermeasures. Satisfactory fuze operation has been demonstrated by a field test in which ten fuzes were fired against a simulated target. (Author)
