AN/SPS-37
The AN/SPS-37 was a naval long-range surveillance radar operating in the VHF band.
It was the direct successor of the AN/SPS-29 and used the same antenna of type AS-943/SPS-29, but equipped with a different IFF antenna (AS-1065/UPX), which was mounted above the common reflector. The AN/SPS-37 got a longer range despite the reduced transmission power of one third because it used a longer transmission pulse and the advantages of pulse compression.
The radar was built in the late 1950s. It was modernized in 1961 to the AN/SPS-37A and used the much larger antenna AS-1092/SP. After further modernization especially in the field of ECCM, it was renamed to AN/SPS-43.
