AN/TPX-46(V)

The AN/TPX-46(V) is a Secondary Surveillance Radar (SSR) series manufactured by Hazeltine Corporation, a subsidiary of GEC-Marconi Electronic Systems Corporation. Models AN/TPX-46(V)1 through (V)6 are interrogator sets designed for compatibility with various missile systems, including the Improved HAWK, and feature interfaces for other radar systems. The AN/TPX-46(V)7, utilized in the Patriot missile system, differs by employing a computer-directed interrogator for single-target evaluation and an Identification Friend or Foe (IFF) antenna integrated into the primary radar antenna, operating at 1030/1090 MHz. This version extensively reuses components from the receiver/transmitter and processor of the (V)1 to (V)6 models, offering selectable peak power of 1,000 or 2,000 W, with its pulse repetition time and frequency synchronized to the primary radar.
