摘要: In the marine study field, it always analysis kinds of acquisition signals to extract meaningful data. this paper, a method wavelet packet transformation (WPT) is suggested analytical ocean signals, such as tidal level in event typhoon. It's known that contains different frequency astronomical components and storm surge components, so can be decomposed by using WPT separate them into serials bands signals. Specifically, process curve extracted independently reconstructing exclusive coefficients for our deeply research future. Taking one typhoon measured levelas an example validation opinion, calculated presented method.Compared with value traditional linear method, shows preferably also has applied significance analysising
