CFOSAT（China-France Oceanography Satellite） scatterometer is the first fanbeam conical scanning scatterometer in the world， which can obtain the observation data of multiple incident angles of targets. The CFOSAT scatterometer ground preprocessing service software generates level-1 data， including L1A （level-1 A） and L1B （level-1 A）data. According to the requirements of CFOSAT scatterometer level-1 data tracking test， a CFOSAT scatterometer data test software system is designed and developed， which focuses on testing and analyzing Sigma0 data. Data test system is based on MySQL database technology， combined with OpenMP parallel processing technology and developed by MATLAB and VC++ mixed programming. It can completely and efficiently obtain the test and evaluation results of CFOSAT scatterometer Sigma0 data quality. The test and analysis of CFOSAT scatterometer Sigma0 data shows the correctness of CFOSAT scatterometer data preprocessing algorithm， and also shows that CFOSAT scatterometer has high observation accuracy. The software is helpful to fully master the status of CFOSAT scatterometer business data， and provides an important reference for the optimization of CFOSAT scatterometer data preprocessing algorithm.
