摘要: 提出了一种顾及潮时差变化的多验潮站多边形潮汐分区改正数学模型,设计了海量多波束数据通用的虚拟单验潮站改正模式。应用结果表明,该模型准确地再现了时变水位场,实现了区域瞬时海面的无缝拼接,较好地解决了多波束条带采用传统潮汐分区改正模型引起的断层及锯齿状问题。Abstract: A mathematical model of tide zoning correction is proposed.Based on the computational model,a new tidal correction mode using single suppositive grid tide station is designed.The numerical test results show that the new method can reveal the time-space variation of water level,and the seamless joining of regional instantaneous sea level can be realized.
