Abstract:
A missile tracking and deflection system for protecting a platform, comprising:a missile warning system for detecting the presence of a missile and generating a warning hand-off signal; a countermeasure processor for receiving said warning hand-off signal and generating a trajectory signal; a track processor for receiving said trajectory signal and generating a pointer trajectory signal; a pointer for receiving said pointer trajectory signal to position said pointer toward the missile; a laser positioned by said pointer, said laser emitting a laser beam at the missile to generate an active signature; and an infrared receiver comprising an infrared focal plane array that integrally and simultaneously combines a tracking camera and a laser receiver, said infrared receiver positioned by said pointer, said camera receiving a passive signature of the missile and generating a trajectory characteristic signal received by said track processor for updating said pointer trajectory signal, said laser receiver receiving said active signature and generating a missile characteristic signal received by said countermeasure processor to identify the missile and generate a jam code carried by said laser beam to divert the trajectory of the missile away from the platform.
