The AN/TPS-43 is a transportable 3-dimensional air search radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman.
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. The TPS-43E2 was redesignated the AN/TPS-75 which 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
Operational History

Radio signals broadcast from a single antenna will spread out in all directions, and likewise a single antenna will receive signals equally from all directions. This leaves the radar with the problem of deciding where the target object is located.
Early systems tended to use omnidirectional broadcast antennas, with directional receiver antennas which were pointed in various directions. For instance, the first system to be deployed, Chain Home, used two straight antennas at right angles for reception, each on a different display. The maximum return would be detected with an antenna at right angles to the target, and a minimum with the antenna pointed directly at it (end on). The operator could determine the direction to a target by rotating the antenna so one display showed a maximum while the other showed a minimum. One serious limitation with this type of solution is that the broadcast is sent out in all directions, so the amount of energy in the direction being examined is a small part of that transmitted. To get a reasonable amount of power on the "target", the transmitting aerial should also be directional. 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.
