Type 349 radar is a fire-control radar for Type 730 CIWS developed by the 20th Research Institute of China Electronics Technology Group Corporation (CETGC, 中国电子科技集团公司第二十研究所), also known as Xi’an Research Institute of Navigation Technology (西安导航技术研究所), with the Chinese naval designation of H/LJP-349.
[1] In addition to CIWS, Some models of Type 349 is also used to control larger caliber guns.
Furthermore, when incorporated as part of CIWS, Type 349 is slaved to Type 730 CIWS gun and thus does not rotate, because the gun rotates when searching/tracking.
[1] The shape of antenna is also an important visual cue to distinguish three radars.
A derivative LR66 can control both the small and larger caliber guns.
