First results from field campaign of spaceborne precipitation radar in China: Radar performance analysis
中国星载降水测量雷达首次校飞试验-雷达性能指标分析

The first Ku/Ka dual-frequency precipitation measuring radar field campaign was carried out successfully from September to October, 2010 in China. Valuable data were obtained from this fi eld campaign, including Ku/Ka dual-frequency airborne radar data and simultaneous observation data over land and sea as well as from spaceborne precipitation radar. Observation results of Ku/Ka-band precipitation measuring radar were presented. Point to point comparison of airborne radar data and vehicle-based X-band meteorological radar data was carried out, and quantitative indices were computed to indicate the observation consistency statistically. Comparisons of airborne radar data with TRMM PR data were made, in order to reveal precipitation measuring radar's ability in detecting rainfall. Detection sensitivity and actual range resolution of airborne precipitation measuring radar were analyzed using observation data to validate Ku/Ka-band radar's performance.
