Active electronically scanned array radar prototype for missile defense

August 08, 2017 // By Jean-Pierre Joosting
Lockheed Martin is unveiling an active electronically scanned array (AESA) Radar for Engagement and Surveillance (ARES) that is a representative full-scale prototype of the technology to support a modern, 360-degree capable sensor to address current and emerging air and ballistic missile threats.

This fractional array is representative of Lockheed Martin's potential Lower Tier Air & Missile Defense Sensor system, built on a modular and scalable architecture to scale to the U.S. Army's requirements, once finalized, to replace the aging Patriot MPQ-65 radar. The array will be used to mature technology and verify performance to ensure uniform 360 degree threat detection and system performance.

"Incremental upgrades to the existing Patriot radar no longer address current sustainment issues, current threat performance shortcomings, or provide growth for future and evolving threats," said Mark Mekker, director of next generation radar systems at Lockheed Martin. "Lockheed Martin is prepared to offer a next generation missile defense system that will leverage advances in radar technology to provide a modular, scalable architecture and reduce the total cost of ownership well over its 30 year lifecycle."

Lockheed Martin's active electronically scanned array (AESA) technology incorporates gallium nirtride (GaN) transmitter technology and advanced signal processing techniques including recently developed and proven 360 degree sensor/fire control algorithms based on advanced threat sets. These technologies and concepts have been fully integrated into both demonstration and production systems resulting in the industry's first fielded ground based radars with GaN technology.

The AESA technology is also in use in the AN/TP/Q-53 radar system, which Lockheed Martin designed, developed and delivered to the Army on an urgent need timeline in under 36 months, and which continues to be scaled to address emerging threats.
