| 摘 要： | 测量不稳定流和受潮汐影响的流量一直是水文工作者所面临的难题。对于工作在海水中的走航式ADCP(声学多普勒流速剖面仪),在测量流速时,受风浪影响,往往引起测量平台的晃动,通过外接光纤陀螺,对平台的姿态进行修正,从而提高ADCP的测量精度。针对典型四波束ADCP建立了在考虑到平台晃动情况下的误差修正模型,仿真结果表明该方法可明显提高测流精度。

| Abstract: | To measure the unstable ocean current and flux influenced by the tide has always been a problem confronting the hydrologists.When seawater velocity is surveyed by vessel-mounted ADCP,Wind and wave will result in flat swaying,which might be modified through external fibre-gyroscope so that measuring precision is improved greatly.In this paper,the error amend model is established toward the typical four-beams ADCP considering flat swaying.The present method turn out to be effective by simulation,which has displayed favorable precision. |
