Northrop Grumman Successfully Tests Three-Dimensional Radar System

Northrop Grumman completed a successful full-scale demonstration of its Three-Dimensional Expeditionary Long-Range Radar (3DELRR) for the U.S. Air Force last month. 

"The U.S. Air Force system variant of the Department of Defense AN/TPS-80 radar performed exceptionally well during this comprehensive demonstration," said Jeff Palombo, vice president and general manager of Northrop Grumman's Land and Self Protection Systems Division. "This mature system is a low-risk solution that can provide significant immediate and long-term development, production and logistics cost savings for our Air Force customer." 

During the demonstration, Northrop Grumman's 3DELRR performed long-range detection and tracking of live aircraft via high-power S-Band Gallium Nitride transmit/receive modules while showing successful system ambient air cooling under extremely hot operating conditions and comprehensive automatic system self-test and calibration capabilities. 

Designed to replace the current AN/TPS-75 radar systems, 3DELRR will be the primary Air Force ground-based, long-range radar for detecting airborne threats. 

Based on Northrop Grumman's active electronically scanned array (AESA) radar technology, the company's 3DELRR solution is a highly mobile, affordable and reliable radar system that will give the Air Force powerful new air defense capabilities.
