摘要: 基于潮位提取理论,给出了三种潮位提取方法,通过与实际观测潮位的比较和分析,认为基于快速傅立叶变换(fast Fourier transform,FFT)的潮位提取方法最佳,实验也证实了该结论的正确性。Abstract: Based on the extraction of tide level theory,three methods of extraction of tide level are given.Through comparison and analysis with the actual observations,it can be concluded that the method based on FFT is best;and the experimental results show the correctness of the conclusions.
