This technology is an optics-based system for covertly identifying objects as friend or foe.
Identification friend or foe (IFF) refers to a communication system or method of distinguishing friendly objects, such as friendly aircraft, from non-friendly objects, such as enemy aircraft. IFF systems can rely on insignia, radar, infrared or thermal identification, or radio communication to locate or identify various objects. However, these types of identification are often not reliable, as they can be jammed, intercepted, or mimicked. As such, there is a need for an improved system for reliable IFF.
This technology is a generic system for covertly making friend or foe (FoF) visual (optics-based) identification of an object. In the case of a concealed object, FoF identification can be made without compromising the camouflage both of the concealed object and of the system that sends the FoF request, highlighting the system’s ability to be hidden and secure. The system operates by superimposing a covert spread spectrum signal on top of the camouflage object signal. As a result, this technology is applicable both to units with traditional camouflage and devices with active camouflage systems, making it versatile and efficient.
