Anybody recognise what this satellite is? Bing translation says. Launch vehicle looks like CZ-5.

"geostationary-orbit interferometric millimeter wave atmospheric detector" is expected to enhance typhoon strong rainfall monitoring and forecasting ability

Prototype for ground testing

Developed by ESA and the Chinese National Space Science Center, this prototype millimetre-wave instrument is designed to sound the depth of typhoons and rain clouds from geostationary orbit. This 3-m diameter prototype, undergoing ground testing in Beijiing, makes use of interferometry to deliver high-resolution images from 36 000 km up. Separate signals from multiple antennas are precisely correlated together to produce a picture of otherwise impossible sharpness.  These antennas are mounted on a circular frame, then set rotating at a rate of once per minute, allowing them to fill in further details. China’s 54 GHz 21-antenna instrument making up the outer circle is called the Geostationary Interferometic Microwave Sounder II, while ESA’s making up the inner circle is the 183 GHz 24-antenna Geosounder II, designed for ESA by Omnisys Instruments in Sweden.
