AN TPS-43
The AN/TPS-43 is a transportable air search 3D radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. It is used primarily for early warning radar, early warning and tactical control radar, tactical control, often for control over an associated surface-to-air missile battery or airfield. It is designed to be transported in two M35 series 2½-ton 6×6 cargo truck, M35 cargo trucks and easily air-transportable on two pallets.

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 pat ...
