AN/SPS-12

AN/SPS-12 was an L-Band, medium surveillance radar which was developed to detect aircraft and surface vessels. The first AN/SPS-12 radar was delivered in September 1953.

The antenna was a truncated metal parabolic mesh fed by a massive feed horn. There was no stabilization vane as the weight of the horn was sufficient. The echo signals were shown on a PPI-scope (general display) and an A-scope (range-only display).

AN/SPS-12 was retired in the 1980s.
