| 摘 要： | 2010年9月-10月成功开展的中国首次Ku/Ka双频星载降水测量雷达校飞试验,获得了宝贵的机载雷达实测数据和地面、海面同步观测数据,以及热带降雨测量卫星所携带降水雷达的同步观测数据。本研究给出了校飞试验中获得的Ku/Ka双频降水测量雷达探测结果;对Ku/Ka频段机载雷达与车载气象雷达数据进行了点对点比较,计算了定量指标,从统计意义上表明观测的一致性;并对比分析了校飞雷达数据与星载降水雷达数据,揭示降水测量雷达仪器的降雨探测能力;利用降雨和晴空海面实测数据给出了Ku/Ka频段雷达探测灵敏度和实际距离分辨率的分析结果,验证了Ku/Ka频段降水测量雷达的性能指标。

| Abstract: | 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. |
