ABSTRACT:
A fuzing system adapted for use by a guided missile to generate a detonation signal for a warhead carried by the missile. The missile has a seeker/tracker to track, and direct the missile towards, a target. The seeker/tracker has: a seeker, gimballed with respect to the body of the missile, for producing a signal representative of the angular deviation between the target and the missile; and, a ranging system for producing a signal representative of a range between the target and the missile. The fuzing system, in response to the range signals, produces a time-to-go signal, t.sub.go, where t.sub.go, related to the range between the missile and the target divided by the rate of change in such range. The seeker produced signal represents the line of sight angle between the missile and the target and wherein the processor, in response to the range signal and the line of sight angle signal produces a miss distance signal representative of a predicted distance, normal to the line of sight, at the time the remaining before the missile intercepts the target. A fragment velocity signal is produced representative of the velocity of fragments of the warhead divided by the predicted warhead miss distance.
