Abstract

This paper present a new approach for wavelet deconvolution. We investigate the use of all- pass operator to change the phase of the minimun-phase inverse filters. the all-pass operator are formed by using roots of the polinomial associated to the Wiener-Levinson filters. By selecting subsets of roots it is possible to generate an ensemble of mixed-phase inverse filters. The ooptimization process to obtain an optimum inverse filter is performance by using a genetic algorithm. we have used the varimax norm as the objetive funtion to mesure the simplicity of the deconvolved seismic trace. the method was tested using synthetic and real seismic data.
