Abstract:
1. A method for countermeasuring an IR guided missile from behind, with a modulated infrared beam from a source behind the missile, the missile, having a seeker dome and launched towards a target, comprising the steps of: detecting the launch of the missile; and directing a modulated infrared beam towards the missile from a direction from behind the missile such that the angle relative to the longitudinal axis of the missile is greater than 90° but less than 170°, the modulated beam causing the missile to go off-target, the seeker dome being made of a high index of refraction material selected to be transmissive at long infrared wavelengths, such that a laser beam having an angle of incidence relative to the optical axis of the seeker greater than 90° but less than 170° is totally internally reflected.
