Abstract
The ultraviolet (UV) band of the electromagnetic spectrum has the potential to be used as the host medium for the operation of guided weapons. Unlike in the infrared (IR) band, a target propelled by an air-breathing jet engine produces no detectable radiation in the UV band and is opaque to the background UV produced by the sun. Successful engineering of spectral airborne IR countermeasures (CMs) against existing two-color IR seekers has encouraged missile counter-countermeasure designers to utilize the silhouette signature of an aircraft in the UV as a means of distinguishing between a true target and a flare CM. We describe the modeling process of a dual-band IR and UV rosette scan seeker using CounterSim, a missile engagement, and countermeasure simulation software package developed by Chemring Countermeasures Ltd. Results are shown from various simulated engagements of the dual-band man-portable air defence (MANPAD) system with a C-130 Hercules. These results have been used to estimate the aircraft’s baseline vulnerability to this MANPAD threat and to develop a model flare countermeasure that is successful in greatly improving the survivability of the aircraft.
