US-made 3D air search radar

The AN/TPS-43 radar set

The AN/TPS-43 is a transportable air search 3D radar produced in the United States originally by Westinghouse Electric Corporation's Defense and Electronic Division, which was later purchased by Northrop Grumman. It is used primarily for early warning and tactical control, often for control over an associated surface-to-air missile battery or airfield. It is designed to be transported in two M35 cargo trucks and easily air-transportable on two pallets.

The TPS-43 uses multiple feed horns and an organ-pipe scanner to rapidly scan its pencil beam vertically while the entire antenna system rotates to scan in azimuth. By comparing the relative power of a return in one or more of the vertical feed horns, the target altitude can be determined. Since its introduction in 1966 it has undergone many modifications. In later versions, the organ-pipe was replaced by a stripline matrix to produce beamforming that had the same output pattern but had no moving parts. Many more upgrades were made to the transmitter and receiver as solid state electronics were able to handle increased power loads.

Among its notable uses were two examples used by the Argentine Air Force that were moved to the Falkland Islands during the 1982 Falklands War. The example at Port Stanley Airport survived two attacks by AGM-45 Shrike missiles before being captured by British forces. It was repaired, upgraded, and then used by the Royal Air Force for many years.

Description

This section needs expansion. You can help by making an edit requestadding to it . (January 2015)

The AN/TPS-43 is a ground-based, non-fixed (i.e.: transportable) search radar. The entire system can be broken down and packed into two M35 trucks for road transport.

An updated version replacing the original shaped reflector and organ-pipe scanner with a phased array antenna was originally known as the TPS-43E2, but emerged as a much more modern system and was renamed the AN/TPS-75. TPS-75 is the current transportable air control and warning (AC&W) radar used by the United States Air Force.

Variants

In addition to the basic TPS-43 several variants were developed.

  • TPS-43A (antenna tilt; new IFF)
  • TPS-43B (enlarged shelter; changes to transmitter)
  • TPS-43C / 43CX (increased reliability; IFF improvements)
  • TPS-43D / 43DX (ISLS added; maximum detection range increased)
  • TPS-43E (major redesign; improvements to electronics, mechanics and shelter)
  • TPS-43F / subvariants V1 to V6 (major redesign; enlarged shelter, improved electronics; increased reliability)
  • TPS-43G (4MW version designed for Pakistan)
  • TPS-43M (improved electronics; increased dynamic range; improved IFF incorporating several modules in a single unit)
  • TPS-430

The AN/TPS-43 completed development in 1963 and entered US service in 1968.

This radar was deployed by the Argentine Air Force during the 1982 Falklands War to Stanley and survived two British attacks with AGM-45 Shrike anti radar missiles on May 31 and June 3. One of the radars was captured by British forces after the Argentine surrender and deployed at RAF Buchan. Another set installed at Rio Grande, in the mainland, was used to guide Argentine attacks on the British fleet.
