Abstract

A countermeasure system for protecting a target against a threat comprising a sensing system including a first sensor(s) for detecting a threat within a wide-angle sector and producing a first directional signal indicative of a first angular zone of the threat location, and a second sensor(s) for detecting the threat within a narrow-angle sector narrower than the wide angle sector and for producing a second directional signal indicative of a relatively narrower second angular zone of the threat location; an illumination source for emitting a beam for neutralizing a threat; a controller for receiving signals from the sensors and for outputting tracking signals; a drive arrangement for moving the second sensor responsive to the first tracking signal to orient the second sensor to face towards the first zone, and beam directing means for directing the beam from the illumination source towards the second zone based on the second tracking signal.

Abstract

A laser jammer configured for being a part of a countermeasure system. The system comprises a stage having an axis of rotation and laser source mounted on the stage. The laser source is configured for emitting a laser beam having an optical axis perpendicular to the axis of rotation. The laser has a first spread in a first plane parallel to the rotation axis of the stage and including the optical axis, and a second spread in a second plane perpendicular to the first plane and including the optical axis. The first spread is greater than the second spread.
