Aplicação de Identificação Cega de Canais À Deconvolução Sísmica

This paper will show preliminary results on a study about the application of a blind identification method to seismic deconvolution. The algorithm consists in an improvement of the idea proposed by Luo & Li (1998), which doesn’t require a white reflectivity and allows mixed phase wavelets. The estimation of the wavelet will be improved by an iterative algorithm based in one of the neural networks proposed by Wang & Mendel (1992), retrieving simultaneously the wavelet and the earth impulse response.
