Abstract
A method of countermeasuring heat seeking missiles is disclosed in which an infrared source is spatially modulated by providing a beam from the source which is swept past a point in space to produce pulsed infrared energy at this point. In one embodiment the beam is swept around a 360° azimuth for omnidirectional protection.
