Successful Demonstration of S-Band AESA Radar Capability for Cobra Judy

Northrop Grumman, BALTIMORE: Northrop Grumman Corporation has designed, developed and successfully tested a new S-band active electronically scanned array (AESA) radar technology intended to provide the U.S. Navy with a smaller, lighter and more capable alternative to current S-band, ship-based radars. 
 
The test, held in March at Northrop Grumman's outdoor integration test facility in Baltimore, utilized a sub-array of the S-band antenna being developed by the company in support of the Navy's Cobra Judy Replacement (CJR) program. CJR is an integrated, surveillance and ballistic missile data collection radar system designed to support U.S. treaty monitoring activities. 
 
The test demonstrated the full power operation of the antenna, including the full pulse width and duty cycle required for the CJR mission. The demonstration also proved the enhanced capabilities of Northrop Grumman's S-band high power transmit/receive modules.
