摘要:

对星载雷达数据与地面降雨资料进行空间匹配,并展开定量分析,在理论研究与实际应用中具有重要意义. 详细介绍了美国戈达德航天飞行中心采用的数据匹配方法,进一步采用了更精细的三维网格,对三组星载与地基雷达数据进行了空间匹配处理,并对结果展开了定性比较与点对点的定量对比,比较了2种匹配方法,验证了匹配方法的有效性.

关键词: 星载测雨雷达, 地基雷达, 空间匹配

Abstract:

Research on spatial matching of spaceborne radar data and ground radar data is important both in theory and application. The data matching method adopted by NASA Goddard Space Flight Center (GSFC) is introduced, and a refined 3-D grid is put forward. Three groups of spaceborne and ground radar data are matched using the two means. Qualitative comparisons and point-to-point quantitative comparisons are made, so as to analyze and test the effectiveness of the proposed method.

Key words: spaceborne precipitation radar, ground radar, spatial matching
