东北地区多普勒天气雷达基数据的共享与应用

Sharing and Application of Raw Data for Doppler Weather Radar in Northeast

摘要: 东北地区现有27个民航运输机场，其中空管系统机场均配备了多普勒天气雷达，目前，空管系统对于天气雷达基数据的使用仅限于雷达站本地，本文根据此现状，设计了东北地区机场天气雷达基数据的共享应用解决方案：针对民航通信网络带宽受限的情况，使用无损压缩技术，极大地提高了基数据的传输时效，解决了基数据传输难以满足使用需求的瓶颈；基于收集到的基数据，设计了基于Oracle的雷达数据管理系统，实现了用户对于数据的高效查询与下载；同时对收集到的各地基数据格式进行了分析与研究，实现了东北地区天气雷达组网拼图，并将拼图产品传输至各分局站，实现气象雷达资源的共享。

Abstract: Now 27 civil aviation transport airports are built in the northeast. The airports of ATMB are all equipped with Doppler weather radar. At present, the use of Doppler weather radar systems for AMTB is limited to the local. Based on this situation, this paper designs a shared application solution for weather radar raw data for the airports in northeast: raw data of radar is losslessly compressed for the limited bandwidth of civil aviation inner communication networks, improving the transmission of raw data greatly and solving the bottleneck of raw data transmission. At the same time, raw data management system based on Oracle is designed, realizing the efficient query and download of users for raw data. The format of raw data collected from various regions is analyzed, achieving the networking of Doppler weather radar in northeast. The products are transmitted to the branch station, achieving the share of the meteorological radar resources.
