| 摘 要： | 针对目前天气雷达存在型号繁多、开机时间不定等问题，提出天气雷达回波图像功率、时间、空间的归一处理方法，将不同雷达的回波图像归一化，为拼图提供统一的数据源，利用重叠区域回波技术构成组网雷达回波图像，采用球面投影技术，得到较为理想的天气雷达区域回波图。

| Abstract: | Due to the differences in locations, types, emissive power, elevation and boot-strap time, etc, of weather radars, a method for normalizing echo image data for weather radar is put forward. The normalization was carried on the power, time, and location of echo data from different weather radar. It provides a reliable data foundation for the concatenation of the regional weather radar echo images. It can use the echo technology over overlapped regions to form the networking radar echo images, thus adopting the sphere projection to get better weather radar echo images. |

| Keywords: | concatenation of radar echo images reflecting factor sphere projection |
