Abstract
An inexpensive, efficient and lightweight integrated small decoy system towed behind an aircraft to power an intense IR emitter for drawing in a missile with an IR sensitive guidance system away from vulnerable parts of a defended aircraft is combined with a system for simultaneously cloaking the aircraft with spectral bands of atmospherically scattered UV solar radiation reflected, and radiated from UV radiant sources mounted on the aircraft to defend against advanced MANPADS missiles with guidance systems sensitive to UV shadows cast by an aircraft in a background sky radiance of atmospherically scattered solar UV. Both the reflected and direct cloaking UV emittance may be spatially and/or temporally modulated to confuse an incoming missile. The UV aspect of this invention may also be combined with other C-MANPADS missiles, such as DIRCM, to provide additional defensive capability.
