      基于导航卫星载波信号的海浪高度反演系统

      Sea wave height retrieving system based on GNSS-R carrier phase

        摘要
      • 摘要: 采用国内首个自主研发的全球定位系统(GPS)载波相位波浪仪,在上海东海大桥24km处的海洋遥感观测基地,构建全球导航卫星系统反射(GNSS-R)海洋遥感观测平台,对自然条件下充分发展的海浪进行观测实验。建立海表反射新模型及方法,推导载波相位差之差反演波高的方法,通过接收GPS直达和经海面反射的信号,选定仰角和信噪比符合条件的信号,经过信号的相关处理运算,输出海面波高的反演结果。利用自动气象站风场资料进行初步的定性分析,结果表明:GPS反演的波高结果基本合理可信,系统运算快速,实时性较强。目前,整个系统已投入业务试运行。

         

        Abstract: The wave observing instruments invented by our team were firstly used in the Global Navigation Sateuite System-reflection(GNSS-R)remote sensing system located at Shanghai East Ocean Bridge.Firstly,a new sea surface reflected model for GPS signal,as well as sea surface height(SSH)retrieving method based on dealing with the difference between the Global positioning System(GPS)carrier phase differences was given.GPS direct and reflect signals received by right hand circular polarized(RHCP)and right hand circular polarized(LHCP)antenna respectively, are then selected and retrieved to SSH.At last,wind data from automatic weather station nearby was preliminary analyzed to confirm the reasonability and creditability of SSH output from the system.So far,the system has run into trial operation for about 1 year.
