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.
