Abstract:

Based on the model and research status of water depth measurement, the basic principles and key technical points of the non-tidal sounding model are expounded. At the same time, the operational mode of non-tidal survey at sea was optimized. And then the application was verified by taking Haiyang ten thousand meters sand beach sea area as an example. The results show that the sounding model based on the non-tidal theory can meet the requirements of the sounding specification from two aspects of internal and external coincidence accuracy. It can be popularized and applied in bathymetric survey of ocean engineering.

Key words: no tide theory, sounding mode, key technology, optimization
