In order to show radar echoes efficiently, this paper states the reflectivity storage format after analyzing the basic data of a kind of new weather radar CINRAD/CB. Then the CB radar's basic reflectivity data, this paper describes two visualization methods depending on the characteristics of vector data and raster data. Moreover, this paper also studies the conversion of reflectivity data from the polar coordinate system to the Cartesian system, and designs a method to show the radar echoes with vector data format and raster data format. Finally, the basic reflectivity data of the CINRAD/CB weather radar in Ordos City are taken as an example, and the result shows that the two methods both can accurately display the reflectivity echo, and that the raster method has a higher efficiency while the vector method is more analytic, each being applicable to its appropriate applications.
