Hilbert-Huang transformation is a newly developed time-frequency analysis method for dealing with the non-linear,non-stationary signals.In this paper,the basic principles and several key technologies of the Hilbert-Huang transform,as well as its strengths are briefly introduced.It s application to the decomposition of seismic signal with random noise included and actual seismic data are discussed also.The original signal can be really reconstructed with this method,and reconstructed signal improves signal-to-noise ratio and resolution of the attributes, so It is a meaningful method for denoising the seismic data.
