SPS-1

The SPS-1[1] was a complex S band three-dimensional maritime surveillance and target acquisition radar.

The antenna system consisted of two parabolic reflectors back-to-back, two linear phased array antennas with parallel feeds for the target tracking radar, an additional slotted waveguide antenna, and an IFF antenna, all enclosed in a large plastic radome. All antennas rotated together on the turntable.

The radar was originally developed under the name AMES Type 988 “Broomstick” and was intended for the Sea Dart weapon system for British warships, construction of which was subsequently discontinued. Hollandse Signaalapparaten continued to develop the radar until 1969 under the designation MTTR. Only two of these radars, renamed to SPS-1, were used in 1975 on the Dutch Royal Navy frigates De Ruyter (F806) and Tromp (F801).

Remark:

  1. Do not confuse SPS-1 with the AN/SPS-01.
