AN/TPY-4
AN/TPY-4 is an operating in the L-Band three-dimensionally measuring active electronically scanned array (AESA) radar that is capable of tracking satellites, detecting low-profile unmanned aerial systems (UAS), and conducting ballistic missile search and tracking. It was selected by the US Air Force to replace the AN/FPS-75 radar.
AN/TPY-4 uses digital beamforming and may rotate in 360 degrees or provides a stop/stare non-rotating mode with 90-degree coverage and a maximum detection range of 1 000 kilometers. The antenna includes 1 152 single radiators in gallium nitride (GaN) technology. AN/TPY-4 can detect and track targets flying at 30 kilometers of altitude as well as surface targets at −6 degrees supporting ground-based maritime surveillance. It can track up to 90 degrees in elevation (no cone of silence) to support a tactical ballistic missile mission.
The radar is available in both fixed- and highly-mobile variants and is transportable via C-130, C-17, truck, rail, or helicopter.
