摘要
广东省气象部门是国内首个开展高频地波雷达探测海面风场试验的气象部门。高频地波雷达可以对海洋环境进行全方位、多手段的立体监测,全天候地实时探测海洋海流、海浪及海风等海态信息。本文分析了阳江高频地波雷达在探测海面风场试验过程中,地波雷达天线场地、雷达站周边环境以及天气、电离层对雷达信噪比的影响,对天线场地的平整、加装反射网、地网等可提高雷达的信噪比。如果能进一步提高雷达的探测性能,提高信噪比,地波雷达将能更好地为海洋气象探测及海洋预报服务。
Guangdong Meteorological department is the first to carry out HFSWR sea surface wind field tests. HFSWR can detect the marine currents, waves and sea breezes and other status information in all domains, multi-dimensional, around the clock real-time.This paper analyzes the impact of the SWR antenna sites, radar stations surrounding environment, the ionosphere on the radar SNR in the Yangjiang HFSWR sea surface wind field tests process. The radar SNR can be improved by installing reflection network and network, and leveling the antenna sites. If we can further improve the detection performance of radar and SNR, SWR will be able to better serve the marine meteorological and marine forecasting services.
