On the methods of seismic data instantaneous attributes estimate in time-frequency domain
Jinguo Wang · Journal of Xidian University · 2005
In order to impvoe the estimate precision of the seismic data instantaneous attributes(IA) in time-frequency domain and so much the better show the strata characteristics,the new method for the reassigned short-time Fourier transform of seismic data is applied.After applying this method to the seismic model and practical seismic data,a conclusion is made that the calculation precision is much higher than that of the method based on the short-time Fourier transform;and the method is very valid for studing the seismic data instantaneous attributes.Extending and the contacting of the strata can be clearly shown too.
