摘要
基于MATLAB对CINRAD/CC雷达基数据文件进行读取和解析,并利用Matlab的图像处理技术对雷达产品进行三维图形的建模和着色,将不同仰角、不同类别的雷达产品形成以三维坐标表示的图像像素集合,实现了CINRAD/CC多普勒天气雷达反射率因子、径向速度、谱宽等产品的三维显示。三维显示的雷达回波产品可通过旋转控制任意改变视角,可以方便、直观地充分观察各仰角层次、各方位角度雷达回波的细节和空间分布情况,便于快捷、直观地了解回波的三维结构特征。
In order to realize the 3D display of the reflectivity factor, the radial velocity, and the spectral widthof CINRAD/CC Doppler Weather Radar, based on MATLAB, the CINRAD/CC radar raw data are extracted and analyzed, and making use of the MATLAB image processing technology, the 3D modeling and coloring of radar products are accomplished. This technique uses the pixel-level image fusion measured by three-dimensional coordinates to indicate radar products of different elevation angles and different categories. Through the rotation, the 3D display of radar echo products can randomly change the angle to display the 3D structure of the radar echo quickly and easily, and the details and spatial distribution of radar echoes from different elevation angles can be observed conveniently and visually for forecasters.
