| Abstract: | Combined with the advantages of wavelet multiscale analysis in gross error detection,the corresponding method of tide level gross error detection is proposed.According to the principle of wavelet decomposition,the detection steps of tidal range are given.Two kinds of experiments were designed based on the measured tidal level data,and the results show that the gross errror detection model based on wavelet multi-scale characteristics can locate the tidal gross error effciently and accurately. |
