| Abstract: | Basing the study of the spherical distance calculation,principle of polar coordinates projection and the data storage format of Doppler weather radar,a high precision grid technology for radar data was achieved. It provides more accurate and general radar data revised in elevation and spherical distance for the application and research in such aspects as radar echo tracing,precipitation calculation optimization and short-term forecast and nowcast. |
| Keywords: | polar projection spherical distance doppler radar grid technology |
