Army Technology:
Raytheon has been awarded a contract to start incorporating Gallium Nitride (GaN) components into the US Missile Defense Agency’s existing and future AN/TPY-2 radars.
The transition to GaN technology is expected to further modernise the ballistic missile defence radar and reduce system obsolescence.
AN/TPY-2 radars currently use Gallium Arsenide (GaAs) based transmit / receive modules to emit high power radiation.
Raytheon integrated defence systems mission systems and sensors business area vice-president Dave Gulla said: “GaN components have significant, proven advantages when compared to the previous generation GaAs technology.
“Through this effort, Raytheon will develop a clear modernisation upgrade path for the AN/TPY-2 radar, enabling the system to better defend people and critical assets against ballistic missile threats at home and abroad.”
The GaN technology has the ability to enhance range, detection and discrimination performance while reducing production costs, Raytheon said in a statement.
The AN/TPY-2 transportable X-band radar protects civilians and infrastructure in the US, deployed military personnel, and allied nations and security partners from the growing ballistic missile threat….
