| 摘 要： | 该文针对贵州CD型号新一代多普勒天气雷达反射率因子,采用C#编程,经坐标转换后处理成三维网格数据,基于双线性内插值法,实现任意方向雷达反射率因子垂直剖面制作,结合贵阳雷达分析,结果表明双线性内插值法放大后的图像质量较高,解决了因垂直剖面图像较小不利于显示及放大的问题。

| Abstract: | The New Generation Doppler Weather Radar Reflectivity factor of Guizhou is transformed to the coordinate transformation into three-dimensional grid data post-processing by C# programming.Based on bilinear interpolation method,Any direction vertical section of radar reflectivity factor is achieved.Combining Guiyang radar analysis,the results showed that the bilinear interpolation method of high quality image amplifier and the method solve for vertical section is smaller and enlarge images. |
