مشخصه فازي موجك لرزه اي و اثر آن در روش MED

Phase characteristic of seismic wavelet and its effects in MED method.

Utilization of MED method for seismic deconvolution which was suggested by Wiggins in 1978 is taken into consideration because it includes no limiting assumption and has a simple and iterative algorithm. This methodʹs operator is only obtained according to the simplicity of output which is verified by varimax norm. Researchers have used norms resembling the varimax norm. Meanwhile, varimax norm because of utilizing toeplitiz matrix in the final equation has less estimation and therefore, more applications. One of the most important characteristics of this method is that no assumption for phase characteristic of seismic wavelet need be considered. In this research, the authors have attempted to study this characteristic by designing MED filter for wavelet with different phase characteristics.
