| Abstract: | Used the tilt tidal data is processing with Hilbert-Huang(HHT).The key strongpoints of this method are that through the empirical mode decomposition(EMD),the signal is decomposed into a series of intrinsic mode function(IMF),and then the Hilbert spectrum in three-dimensional time-frequency space is obtained. |
