雷达数据传输方式的改进及时效性分析

摘要

The transmission mode and timeliness of single station radar data transmission and interprovincial radar data exchange are analyzed.The influencing factors of radar data transmission timeliness and the improvement measures are given.The results show that by using the single radar data transmission based on ROSE and regional radar synchronization observation,it can be ensured that radar base data and products of the province and the surrounding to reach the forecasters' desktop within 1 minute.Compared with the inter-provincial radar data from the new generation communication system,the regional synchronous observation requires less communication bandwidth and higher time effectiveness.The improvement of the radar data transmission and communication line,and the operation of the integrated use of a variety of real-time transmission modes are introduced,which provides a reference for the improvement of radar data transmission in order to meet the timeliness requirement of meteorological service for radar data.%对单站雷达资料传输、省际雷达数据交换的实现方式与时效性进行分析,给出影响雷达数据传输时效的影响因素及改进措施.结果表明采用基于ROSE的雷达单站资料传输和区域雷达同步观测可确保本省及周边雷达基数据和产品在1 min之内到达预报员桌面,与通过国内新一代通信系统进行省际雷达数据推送相比,区域同步观测对通信线路带宽要求更低,时效更高.介绍了雷达数据传输及通信线路的改进方式及综合运用多种实时传输方式的业务运行方案,为雷达数据传输方式的改进和提高提供参考,满足气象业务对雷达资料的时效性要求.
