ABSTRACT:
A countermeasure system, adapted for use on board an aircraft, for confus an incoming missile as to the location and heading of the aircraft. The countermeasure system generates for each side of the aircraft at least two infrared energy images which are projected onto the aircraft's fuselage and then swept across the aircraft's fuselage to confuse the incoming missile's infrared seeker. Each infrared energy image is generated by at least two lasers operating at different frequencies within the infrared region of the electromagnetic spectrum. A beam combiner combines the beams of infrared energy from each laser forming a single collimated beam of infrared energy having multiple frequencies which is then directed to a beam former. The beam former spreads the collimated beam of infrared energy which it then directs to a scanner. The scanner, which is mounted in a wing tip pod on the aircraft, directs the collimated beam to the fuselage of the aircraft sweeping the beam of infrared energy over the fuselage of the aircraft to confuse the infrared seeker of the incoming missile as to the flight path of the aircraft.
