Type 909
Type 909 served as operating in C-Band target-tracking, illuminating and missile-guidance radar for the Sea Dart GWS 30 missile system and was installed in pairs in Type 42 and 82 destroyers. It has ECCM which are incorporated to counter both active and passive ECM.
The antenna is of the Cassegrain type and has a diameter of 2.44 m. The small radome mounted near the top of the main reflector houses an associated IFF antenna. On board ship, the complete antenna assembly was protected by a radome.
