随着雷达技术的发展成熟，我国相关单位成功研发了一套具有自动观测、自动传输数据、自动分析计算功能的雷达测雨系统。为了验证雷达测雨系统的测量精度，在分析雷达系统测量原理、组成和功能的基础上，选择地面雨量站密度较高的云南洱海地区，进行了点雨量与面平均雨量精度的比较分析工作。结果表明，雷达测雨系统测量精度较高，测量范围较大，具有科学性、可行性、可用性，推广雷达测雨系统可为立体化水文观测、专业化水文服务及应用和水资源精细化管理提供强有力的支撑。

With development of radar technology, China developed a set of radar rainfall observation system with the functions of automatic observation, automatic data transmission and automatic analysis and calculation. For verifying the accuracy of this system, on the basis of analysis on the observation principles, composition and function, the area of Erhai lake in Yunnan Prov-ince, where the rainfall stations were densely distributed, was selected to conduct comparison and analysis on observation accura-cy of point rainfall and non-point rainfall. The analysis results showed that radar rainfall observation has a high observation ac-curacy and wide observation scope, possessing scientificity, feasibility and applicability. The application of radar rainfall observa-tion provides support for 3D hydrological observation, professional services and application as well as fine management of water resources.
