摘　　要：对基本反射率产品进行可视化,是准确分析区域天气的基础。本文以梅州市CINRAD/SA型雷达该类产品为例,对该类数据的存储结构做了详尽的剖析,设计了产品径向数据向二维矩阵转换的算法,研究了该类数据转为极坐标系下矢量类型和直角坐标系下栅格类型存储的绘制模式,并采用ArcGIS Engine进行了实现。最后对两种生成显示回波的方法进行对比分析,结果表明:两种方法都能准确显示回波,应用时需根据实际情况采用相应的方法显示与分析雷达回波。Visualization of the basic reflectivity products is the basis of analyzing region weather.Taking the products of CINRAD/SA weather radar in Meizhou city for example,this paper introduced the storage structure of this type of data in detail firstly,and then,it designed the translation algorithm from this type of data into two-dimensional matrix,and studied the drawing mode of converting this type of file to the vector files under the polar coordinate system and the raster files under the rectangular coordinate system,and also realized it by ArcGIS Engine.In the end,it contrasted and analyzed the advantages and shortcomings of the two methods of converting the echo data,and drew the conclusion that both methods could accurately display echo and the approaches to display and analysis of the radar echoes depend on the direction of research and practical use.
