WASHINGTON, Oct. 13 By Ryan Maass (UPI)
Raytheon announced major milestones bringing an upgrade of Patriot Air and Missile Defense System radar with Gallium Nitride-based Active Electronically Scanned Array radar closer to production phase. Raytheon is funding an upgrade to the Patriot radar as more advanced drones, aircraft, and ballistic missiles are likely to become a greater threat. The upgrade is a Gallium Nitride-based AESA technology, which uses three antenna arrays mounted on a mobile radar, allowing coverage in all directions. Ralph Acaba, vice president of Integrated Air and Missile Defense at Raytheon's Integrated Defense Systems business, says the upgrade will balance more coverage with mobility.
