Abstract：Analysis of independent components,as a new signal processing tool, its application in seismic signal processing region has been preliminarily discussed by many scholars. Based on adaptive Gauss hybrid blind deconvolution presented by Mr. San-tamaria et al and in combination with Bussagang deconvolution algorithm in analysis of independent components, the paper improved negative entropy rule-based objective function by introducing constraint item and constructed new non-linear operator; meanwhile, using the updated expected maximization (EM) algorithm to optimize the parameters of Gauss hybrid model of reflection coefficient, successfully implementing the blind deconvolution of seismic signals. The results of numeric simulation and practical data processing showed that the approach could be better suitable for non-minimum phase system,obtain the optimum evaluation of raw reflection coefficient and be characteristic of fast convergence and high precision, which is effective tool for improving the resolution of seismic data.
