Patent ID: 7521655

Claim:
A method for protecting a civil aircraft from missiles with infrared seeker heads of portable anti-aircraft missile complexes, the aircraft having an engine with a level of radiation power, the method comprising the steps of: detecting a launch of a missile from a location of launch, the missile having an infrared seeker head with an infrared sensitivity range, a power and an operation frequency; continuously determining instantaneous coordinates of the missile in flight after the launch; generating pulsed laser radiation, wherein a wavelength range of the pulsed laser radiation is within the sensitivity range of the infrared seeker head, a power of the pulsed laser radiation exceeding the power of radiation of the aircraft engine in the sensitivity range of the infrared seeker head, and a pulse repetition frequency of the pulsed laser radiation being at about the operation frequency of the infrared seeker head; and sending the pulsed laser radiation to the instantaneous coordinates of the missile in flight.
