新一代天气雷达基数据的3种内插填充方法

Interpolating and Filling Methods for Processing Basic Data of New Generation Weather Radar

简单介绍新一代多普勒天气雷达基数据的格式和结构,对3种从径向基数据到直角坐标图像的转换和填充绘图方法,结合龙岩气象雷达站的实际应用情况进行了比较分析。结果表明,在这3种方法中,弧线填充法在程序设计中方便实用,且实际图像效果也较好。

A brief introduction is conducted to the format and structure of new generation Doppler weather radar base data, and a comparative analysis is made of the transformation of images from radial base data to rectangular coordinates and three interpolating and filling methods, in combination with the practice at the radar station of the Longyan Meteorological Bureau. The results indicate that among the three methods, the arc-curve filling method is most convenient to use and practical, and provides better-quality images.
