摘要
基于北斗卫星导航系统在亚太地区的良好覆盖能力,利用中国气象局、山东气象局及北京航空航天大学在威海联合开展的北斗反射信号海洋遥感试验所采集的海风海浪系统的探测数据与同址同期的浮标数据,着重对北斗GEO卫星反射信号(BDS-GEO-R)探测海面有效波高的可行性进行了分析和检定,并对比分析同期浮标数据.结果表明,北斗反射信号探测海浪结果与浮标数据具有良好的一致性,海面浪高的探测精度为10 cm.最终证明了利用北斗反射信号探测海洋浪高的可行性.
Abstract
Based on good coverage capability of Beidou satellite navigation system in the Asian-Pacific Region,using detection data of ocean wave and buoy data collected by CMA,SMA,Beijing University of Aeronautics and Astronautics,the feasibility of detecting significant wave height by BDS-GEO-R was analyzed,and compared with buoy data.The result of significant wave height showed a good consistence between BDS reflectometry and buoy,and the accuracy was 10cm.Ultimately,it proves the feasibility on detecting ocean wave height using BDS reflected signal.
