Classification: F41G,G01S

Abstract:
A missile tracking and diverting system, comprising:a countermeasure processor for generating a trajectory signal of a detected missile; 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 and track the trajectory of the detected missile; a laser positioned by said pointer; 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 countermeasure processor simultaneously generating an initiation signal and a blanking signal, said initiation signal causing said laser to generate a periodic pulsed signal that includes a laser pulse within a laser pulse interval, said blanking signal instructing said focal plane array to initiate a hold-off time which is longer than said laser pulse, prior to turning said infrared receiver on so as to allow for back scatter decay, said countermeasure processor generating a jam code for inclusion with said periodic pulsed signal to divert the trajectory of the detected missile.
