GaN-based AESA radar delivers high reliabilty, 360-degree capability

May 25, 2017 //By Jean-Pierre Joosting
The latest integrated air and missile defense radar from Raytheon Company based on GaN technology – an Active Electronically Scanned Array proposed upgrade to the Patriot™ Air and Missile Defense, has surpassed more than 1,000 hours of operation in just over a year, which is half the time of a typical testing program.

During the course of the 1,000 hours, Raytheon's GaN-based AESA prototype radar routinely demonstrated 360-degree capability by working together with a second GaN-based AESA antenna that was pointed in a different direction. As targets flew out of one array's field of view and into another, the two arrays seamlessly passed information back and forth, tracking the target continuously. The main array also detected and tracked tactically maneuvering fighter jets and thousands of other aircraft.

"Raytheon's GaN technology is backed by 19 years of research and $300 million in investment, while our competitors are either new to the market or primarily build GaN for commercial applications," said Ralph Acaba vice president of Integrated Air and Missile Defense at Raytheon's Integrated Defense Systems business.

Raytheon's GaN-based AESA radar will work with the Integrated Air and Missile Defense Battle Command System and other open architectures. It maintains compatibility with the current Patriot Engagement Control Station and full interoperability with NATO systems.

A number of current and expected future Patriot Air and Missile Defense System partner nations in Europe and Asia have expressed interest in acquiring GaN-based AESA.
