Patent ID: 7920255

Claim:
A laser directed infrared countermeasures “LDIRCM”) system mountable on a platform, comprising: a plurality of operatively independent sector units, each sector unit comprising: a semiconductor laser unit adapted to produce a laser beam for jamming a guidance system of a threat; a controller for controlling operation of the semiconductor laser unit and for providing drive signals to the semiconductor laser unit; a laser guidance module, the laser guidance module being adapted to steer at least the laser beam generated by the semiconductor laser unit towards the threat, thereby enabling jamming of a threat within a certain sector relative to the platform, and a plurality of threat detection and tracking modules mountable on the platform, such that each one of the plurality of threat detection and tracking modules is configured to detect a threat located within a different sector relative to the platform, which results in a combined threat detection and tracking capability that covers substantially the full perimeter of the platform, and wherein the sector units are mountable on the platform, such that each one of the plurality of operatively independent sector units is configured upon receiving electrical energy to operate independently to provide a jamming capability for a threat located within a respective sector relative to the platform, which results in a combined missile jamming capability that covers substantially a full perimeter of the platform, and wherein at least one threat detection and tracking module of the plurality of threat detection and tracking modules is rigidly attachable to one or more of the plurality of operatively independent sector units that are mounted on the platform, such that tracking data provided by the at least one threat detection and tracking module to the sector unit is substantially unaffected by physical distortions of the platform.
