Abstract

The seismic signal is non-stationary signal, which needs to be introduced into the time frequency conversion method. EPAH is provided in this paper, which uses HHT to deal with the non-stationary seismic signal. The advantage of HHT using in processing non-stationary seismic signal is utilized in EPAH. Firstly, EMD is used to decompose the most significant information and energy of the seismic signal. Then, more low frequency information can be identified by spectrum conversion, so the relationship between time and frequency and power of seismic signal can be obtained. At last, the application of EPAH in time-frequency analyze is verified by matlab. It is shown that all kinds of feature of seismic signal can be obtained exactly.
