Abstract 1. In an infrared gated radio fuzing system for use in a guided missile the combination comprising: A. FIRST THERMAL-ENERGY DETECTING MEANS FOR PRODUCING AN OUTPUT SIGNAL IN RESPONSE TO INTERCEPTED THERMAL-ENERGY RADIATED FROM A THERMAL-ENERGY RADIATING OBJECT, B. SECOND CIRCUIT MEANS FOR DETECTING RADIO ENERGY REFLECTED FROM SAID THERMAL-ENERGY RADIATING OBJECT, C. PULSE GENERATOR MEANS COUPLED TO SAID THERMAL-ENERGY DETECTING MEANS FOR GENERATING AN OUTPUT PULSE HAVING A TIME DURATION APPROXIMATELY EQUAL TO THE TIME REQUIRED FOR THE MISSILE TO TRAVERSE A DISTANCE OF HALF THE LENGTH OF THE RADIATING OBJECT, D. SWITCHING MEANS COUPLED TO SAID PULSE GENERATOR MEANS AND TO SAID SECOND CIRCUIT MEANS AND BEING RESPONSIVE TO SAID OUTPUT PULSE FOR ACTIVATING SAID SECOND CIRCUIT MEANS AND BEING RESPONSIVE TO THE CESSATION OF SAID PULSE FOR DE-ACTIVATING SAID SECOND CIRCUIT MEANS, E. THIRD CIRCUIT MEANS RESPONSIVE TO AN OUTPUT SIGNAL FROM SAID SECOND CIRCUIT MEANS IN THE EVENT A DESIRED TARGET IS DETECTED DURING SAID PREDETERMINED TIME INTERVAL FOR ACTUATING A DETONATION CIRCUIT.

Claim 1
Independent Claim
166 words
In an infrared gated radio fuzing system for use in a guided missile the combination comprising: a. first thermal-energy detecting means for producing an output signal in response to intercepted thermal-energy radiated from a thermal-energy radiating object, b. second circuit means for detecting radio energy reflected from said thermal-energy radiating object, c. pulse generator means coupled to said thermal-energy detecting means for generating an output pulse having a time duration approximately equal to the time required for the missile to traverse a distance of half the length of the radiating object, d. switching means coupled to said pulse generator means and to said second circuit means and being responsive to said output pulse for activating said second circuit means and being responsive to the cessation of said pulse for de-activating said second circuit means, e. third circuit means responsive to an output signal from said second circuit means in the event a desired target is detected during said predetermined time interval for actuating a detonation circuit.
