摘要
用(HHT)Hilbert-Huang方法分析了倾斜固体潮数据,即通过经验模态分解,将信号分解成一系列本征模态函数,再通过Hilbert变换得到三维时频空间的Hilbert谱。
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.
