AN/TPS-43

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.

By comparing the relative power of a return in one or more of the vertical feed horns, the target altitude can be determined.

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.

The example at Port Stanley Airport survived two attacks by AGM-45 Shrike missiles before being captured by British forces.
