Raytheon Corp. discussed its AN/TPY-2 radar and calling him is more powerful than its rivals’.

According to the company’s statement, its AN/TPY-2 is the world’s most capable mobile radar for ballistic missile defense.

AN/TPY-2 can see ballistic missiles at vast distances. It’s designed for discrimination — distinguishing between an actual menace and non-threats such as launch debris or countermeasures. For this critical task, the radar relies on an intricate chain of technology.

“The AN/TPY-2 was already a high performer; a Porsche of a radar,“ said Bryan Rosselli, director of missile defense programs at Raytheon. “Now we’ve gone beyond that. We are upgrading key elements to use the most advanced technology, which further enhances system performance.”

Along the surface of its antenna, transmit and receive modules generate and capture electromagnetic waves that enable the radar to see its environment. A recent U.S. Missile Defense Agency contract paved the way for AN/TPY-2 to use Raytheon’s proven gallium nitride semiconductor technology in its antenna components.

GaN transmit/receive modules will amplify signal power beyond what was previously possible, creating a radar that sees further and stops ballistic missiles sooner.

“GaN is what you want in a radar antenna, because it’s better at handling the heat,” said Jim Bedingfield, director of international missile defense. We’ve refined our GaN production to get the best thermal conductivity, so the electronics are more reliable at higher power levels.
