利用CINRAD/SC新一代天气雷达系统支持组播传输的功能，将组播技术应用于雷达资料实时共享网络的组建中，在已经建成的市县宽带网络基础上，实现市到县雷达数据实时共享，使县级台站除不能对雷达工作方式进行控制外，对雷达回波的其他显示功能和地图信息设置均等同于雷达站，解决了以往雷达资料共享中因雷达完成体扫、数据存储、数据上传和下载等环节所造成的延时问题，为基层台站依据雷达回波实时变化特征，及时准确地指挥人影作业提供了保障。

The multicast technology is applied to the establishment of the realtime radar data sharing network by means of the function of newgeneration weather radar system CINRAD/SC in support of multicast transmission. Based on the existing broadband network, the realtime radar data sharing from citylevel to countylevel could be achieved, which allows county stations to select, except the mode control of radar operation, the functions of the radar system, such as image display and map information setting and resolved the problem of time delay in the previous radar data sharing due to body sweep, data storage, data upload and download. The establishment of the realtime sharing network can help provide guarantee for weather modification operation timely.
