Preliminary Results of the CFOSAT Scatterometer

The scatterometer (SCAT) onboard the China-France Oceanography Satellite (CFOSAT) is the first rotating fan-beam scatterometer (RFSCAT) in space for global ocean surface vector wind measurement. After the CFOSAT launched in Oct. 29, 2018, the main performances of the CFOSAT scatterometer (CFOSCAT) are being tested in orbit. In this paper, the preliminary data processing results of CFOSCAT are presented, including the calibration signal analyses, system noise analyses, normalized radar cross section (NRCS) processing results and wind retrieval results. The results show that CFOSCAT works properly in orbit, the main system specifications of scatterometer system satisfies the design. Preliminary results also validates the wind retrieval performance.
