Patent number: 7688247Abstract: A DIRCM (Direct IR Counter Measures) system includes a detection and warning apparatus for detecting a missile that might pose a threat on the platform to which said system is allocated, and for generating a warning of its existence. The warning may include data that enable the calculation of the expected direction from which the missile is approaching. The DIRCM system may also include an acquisition device for performing acquisition of the approaching missile in accordance with the data provided by the detection and warning apparatus, and issuing data that may enable the calculation in real time of the updated position of the missile, a fiber laser for generating a laser beam, and a motion and aiming enabled turret, coupled with the laser, for directing the laser beam onto the approaching missile.Type: GrantFiled: June 3, 2004Date of Patent: March 30, 2010Assignee: ELOP Electro-Optical Industries Ltd.Inventors: Israel Anschel, Vladimir Krupkin, Andrew Lovett, Zachary Sacks, Doron Chomski, Zeev Schiffer, Kuti Grossman, Elena Luria, Doron David, Itamar Shoshan
