A method for random noise attuation based on optimization prediction filter
LV Qiu-ling · Progress in geophysics · 2012
The paper proposed an optimization prediction filter to pressing random noise in low-S/N seismic meterial.Through modifying AR model mathmatics function,involving deconvolution cost,we developed recurrence algorithm to suppresing random noise.It better than quadratic constraint in convergence rate,and the algorithm achieved single-trace filter,protected effect signals's detail part.Synthetic and real seismic meterial testing indicate this methods can suppress random noise effectively in low-S/N seismic meterial,at same time protecting effect signals well.
