The AN/TPY-4, formerly known as the TPY-X, is a ground-based, active electronically scanned array, L-band, multi-function long-range 3D radar for air defense surveillance, built by Lockheed Martin. [2]
Contents
It is a radar capable of multi-mission operation, and perform simultaneously the following work:
- air surveillance
- low profile UAS detection
- ballistic missile search and track
- maritime surveillance
- 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 electronic systems.
The system is composed of:
- the Transceive Group (TG), the radar system,
- the Processor Group (PG), that has the generator for the radar system and that processes the data of the radar,
- the Ancillary Group (AG), the transport mean.
