| 摘 要： | 713型气象雷达为我国自主设计的固定式测雨雷达,目前我国西北部和中部地区的一些气象局仍在使用。文章简要介绍了713雷达的平面位置显示器(PPI)和距离高度显示器(RHI)两种数据的结构和格式,在充分解析后,采用Visual Basic.NET2005开发语言,完成了对两种雷达回波数据的准确判读。并结合GIS二次开发组件MapX,采用常规天气雷达数据产生回波图像的算法,提出并实现了极坐标系下的雷达平显回波图和高显回波图的地学线型与面型可视化,最大限度恢复了雷达数据中存储的回波信息,为准确分析区域降水提供了依据。 |

| Abstract: | The structure and format of 713-model radar data,Plain Position Indicator（PPI） and Range Height Indicator（RHI）,are introduced briefly.After fully analyzing,the interpretation of radar data is completed accurately by using Visual Basic.NET 2005.Selecting MapX as the secondary development components,the geo-visualization of radar data by both line and region is realized under the polar coordinate system,including PPI and RHI,by means of the traditional algorithms of creating radar images.The method can recover,to the utmost,the echo information of radar data and provide an accurate analysis basis for regional precipitation. |
