【摘要】 研究星载测雨雷达的数据处理方法对于理解测雨雷达系统、开展数据应用以及研制星载气象雷达、开发反演算法等具有重要的意义。该文使用星载测雨雷达的真实数据计算了雷达反射率因子,以较小的计算量获得了准确的表面雷达截面积和路径积分衰减,并研究了降雨分类;得到了台风三维数据处理的图像结果。所得到的处理结果可为理解降水的内部结构与降水机制提供重要信息。更多还原

【Abstract】 Researching data processing of the spaceborne precipitation radar is very important in understanding this unique radar system and developing data application,and will help to design spaceborne weather radar and develop algorithms in the future.Radar reflectivity factor is retrieved using observation data;surface radar cross section and path integration attenuation are calculated with less computation.Rain type classification is also studied and the final results are presented.Typhoon data are processed and some pictures illustrating its 3D structure are given.These results can provide valuable information about internal structures as well as mechanism of precipitation.更多还原
