The Type 347G "Rice Bowl" I-band fire-control radar is found on Chinese Navy ships, in conjunction with the Type 76A dual-37mm automatic AAA gun.
In the 1980s, China imported the OTOBreda (now OTO-Melara) Twin Fast Forty AAA [1] and Selenia (now AMS) SPG-74 (RTN-20X) fire control system from Italy for evaluation.
Although the Chinese navy didn't deploy the twin-40mm AAA, there are some similarities between the Type 347 and the SPG-74 radar, leading some commentators to claim that the Type 347 is based on SPG-74 technology.
[3] The distinct recognition characteristic of the Type 347 radar is the inverse cassegrain antenna with twisted polarization.
[3] The shape of antenna is also an important visual cue to distinguish three radars.
