Study on the Detection and Repair Method of the Short-Period Tidal Gauge Observation System Error

  • The system error contained in the temporary tidal information would have a great impact on the water level correction and computation of the theoretical bathymetrical datum,and not easy to find,especially the zero point of pressure-type tide gauges gradually sinking.This paper presents a self-segmented tide sequence matching method which is based on the least squares.Through analysis system error type,determination of length of sub-section and specific time of sinking,algorithm research of detection and repair,ultimately implement the accuracy detection and precision repair of different type of tidal system error in the temporary tide gauge,and tested by the experiment.
