Lockheed Martin Develops Digital Array Row Transceiver Tech For Radars

Based on the use of Gallium Nitride (GaN) technology, the Digital Array Row Transceiver (DART) results in greater performance within current Lockheed Martin radar products, lowers life-cycle costs and increases energy efficiency.

GaN is a low-risk solution whether part of a systems upgrade or in a newly built system, a company release said.

DART improves upon Lockheed Martin’s ground-based radar products. This new technology is available in the recently launched TPS-77 Multi Role Radar system and is fully compatible with legacy products and can help extend a radar’s useful life.

“This technology is based in part on feedback we have received from customers with whom we’ve developed strong partnerships with over decades,” says Mark Mekker, Lockheed Martin director, surveillance radar. “We are excited to offer this enhanced technology to all our ground-based radar customers.”

Lockheed Martin unveiled DART at its regular radar users’ conference in Orlando, Florida. Representatives from more than 25 countries attended the unique event where they learned from Lockheed Martin experts and shared best practices.

Lockheed Martin has produced and maintains more than 175 surveillance-range radars, all of which are operational around the world detecting targets at ranges up to 250 miles, 24 hours a day. These radars are capable of operating completely unmanned and many have performed for decades in remote, inhospitable areas and in a wide range of operational environments.
