CWS-2

CWS-2 (abbr. of Combined surface and air Warning Ship-borne) was two-dimensional, operating in S band surface surveillance and air surveillance radar.

The rather narrow reflector antenna provided a Cosecant squared antenna pattern. The transmitter used tuneable magnetrons in two frequency sub-bands (2.7 … 2.9 GHz and 2.9 … 3.1 GHz).

The radar was used on the Danish frigates of the “Peder Skram” class in the early 1970s. It remained operational until the 1990s. The frigate “Peder Skram” can be seen in the Copenhagen Naval Museum as a museum ship with its two radars CWS-2 and CWS-3.
