AN/SPS-43 (aka “Bedspring Radar” or “Giant Bedspring”) was a ship-based, 2-dimensional, air-search radar operating in VHF- and used for guided-missile cruisers and aircraft carriers. It uses a co-linear broadside antenna with 20 dipoles that looked like a bedspring.
It is a direct successor to AN/SPS-37 entered service in mid-1961. It used an antenna nearly identical to the earlier radar. The main difference is a greatly improved ECCM performance, the AN/SPS-43 jumps between 20 different frequencies to frustrate jamming attempts. A total of 49 of these radars were delivered during the 1960s. After several years of service with the US Navy, it was replaced by AN/SPS-49.
