laser jamming

laser jamming

[′lā·zər ¦jam·iŋ]
(ordnance)
An electronic countermeasure in which a continuous-wave laser directs jamming energy back to a hostile laser receiver to prevent it from interfering with the use of laser rangefinders, radars, and tracking equipment during an attack.

According to Elettronica, the system is 'readily exportable', not being affected by export limitations (ITAR regulation), and allows the customer to load proprietary laser jamming code libraries.
Northrop Grumman and BAR Systems are poised to begin testing different on-board laser jamming prototypes aboard airliners belonging to two US carriers during August.
A significant performance improvement can be achieved if sufficient IRCM-laser energy is available to radiate laser energy over a much wider spot size and initiate laser jamming with the remote designate signal from the search radar.
These performance tests illustrated the missile's resistance to numerous infrared decoys and electromagnetic radiation immunity--earlier ground trials revealed the seeker's resistance to laser jamming as well.
NH) AN/ALO-157 lamp-based IR jammers and replace them with what the announcement termed "an IRCM system with a multiband laser jamming source." NED has leamed that this will be the Northrop Grumman Large Aircraft IRCM (LAIRCM) system.
The Airborne Laser Jamming System (ALIS) is a pod-based unit that can be carried by a fighter aircraft on a pylon, and can be adapted for larger aircraft, including commercial airliners.
Unlike the existing ALQ-144 jammer, which generates a dumb, omni-directional "bubble" of IR energy around the airframe, the ATIRCM system must automate a seamless response of missile warning and laser jamming to spoof threat missile seekers at a distance, complemented with smart flare dispensing.
One source posited that SOCOM may wait to see which company -- BAE Systems or Northrop Grumman -- reaches the production stage for the laser jamming source first.
The company will demonstrate its Defense Avionics Receiver Transmitter (DART) system and its capability to provide stabilized threat tracking and high-power laser jamming to protect tactical fighter aircraft from IR-guided missiles.
