| 摘 要： | 水位控制是海底地形测量资料处理的重要技术环节之一,潮汐观测数据质量控制则是提高水位改正精度的关键。针对当前自容式压力验潮仪使用中经常会遇到的潮汐观测数据缺失、波浪扰动影响等技术难题以及海水密度精密改正、基准面传递确定等技术需求,开展了相关理论方法研究并开发了较实用的潮汐数据处理模块。结果表明,经多个环节的精密处理后潮汐观测数据精度提高明显,适用于海底地形测量水位改正及其他海洋工程应用。

| Abstract: | Water level control is the main technique in data processing of the bathymetry.The precision of water level correction is originally impacted by the quality of the tidal observation data.Aiming to solve problems of data missing phenomenon and weave disturbing in the tidal observation data with pressure tide gauge,the correlative theoretic research has been discussed and the physical tidal data processing module has been designed and developed,which can meet the need of the precision seawater density correction model and the depth datum transform model.The results show that the tidal data precision can be obviously improved after several processing steps,the method and the physical tidal data processing module can be widely applied in the water level control of the bathymetry and other marine engineering. |
