It is a radar capable of multi-mission operation, and performing simultaneously the following work: air surveillance, low profile UAS detection, ballistic missile search and track, maritime surveillance, and satellite track.
In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/TPY-4" designation represents the 4th design of an Army-Navy electronic device for ground transportable surveillance radar system. The JETDS system also now is used to name all Department of Defense and some NATO electronic systems.
The system comprises:
- Transceive Group (TG), the radar system,
- Processor Group (PG), that has the generator for the radar system and that processes the data of the radar,
- Ancillary Group (AG), the means of transport.
