Engineers electrical systems division of Northrop Grumman in Rolling Meadows (Illinois,) have developed a new generation of infrared detector with increased resolution for the export version of the anti-aircraft missile system of medium-range Hawk.
Northrop Grumman has made the fourth generation of the detector support 4G TAS (Fourth Generation Tracking Adjunct Sensor) to update optronic and infrared detectors in the system «Hawk».
System developed by Raytheon «Hawk» was developed to engage aerial targets. The missile entered service in 1960 and was decommissioned in the U.S. Armed Forces in 2002. In the U.S. Army they were changed in 1994 complexes Patriot, in the United States Marine Corps — Stinger missiles in 2002.
The missile is also produced in Western Europe, Japan and Iran, was coeval complexes Russian SA-3 and SA-6.
Modernization of Northrop Grumman «Hawk» in the basal configuration includes a new infrared detector 640×480 pixels, which will own resolution twice that in today’s system, the company said.
Update will also include the latest camera CCD (charged-coupled device), which is incremented resolution and do a better job in the criteria for low light. The update includes a more reliable and stable electronics. All available system TAS, Improved TAS and Advanced Infrared TAS can be upgraded to the level of 4G TAS.
Infrared detector detects and 4G TAS accompanies low-flying targets fast funny day and NIGHT MODE and transmits them to the fire control radar «Hawk.»
4G TAS is stabilized detector of high resolution, which provides air defense system Hawk passive infrared search and launch support. It can provide a risk assessment and identification beyond visual range, providing real-time situational awareness, argue in Northrop Grumman.
