| 摘 要： | 新一代天气雷达故障直接影响数据质量,异常产品的产生对短时临近预报预警带来了重大的影响,实现雷达异常产品实时监测具有一定现实意义。本系统采用WinForm 3层架构+ORM模型架构,通过统计纹理分析、灰度图像特征值分析等图像处理技术实现自动识别雷达异常产品。新一代天气雷达产品故障监测预警系统可以实时、高效、准确检测出异常雷达产品,满足强对流天气预警监测、天气雷达故障预警服务预判、天气雷达产品可用性服务等功能要求,从单部雷达产品数据中识别出异常回波,避免进一步影响多雷达组网拼图,对天气雷达组网产品的质量控制具有重要的意义。

| Abstract: | The fault of the new generation of weather radar directly affects the data quality. The generation of abnormal products has a great impact on the short time approaching forecast and early warning. It is of certain practical significance to realize the real time monitoring of radar abnormal products. This system uses the WinForm three layer architecture and ORM model architecture through statistical texture analysis, grey image feature value analysis and other image processing technology to realize automatic recognition of radar abnormal products. The new generation of weather radar product fault monitoring and warning system can detect abnormal radar products in real time, efficiently and accurately, and meet the functional requirements of severe convection weather warning and monitoring, weather radar fault warning service prediction, weather radar product availability service, and identify abnormal echoes from the data of a single radar product. It is of great significance for the quality control of weather radar networking products to avoid further influencing the multi radar networking puzzle. |
