【Abstract】 In the light of seismic oil exploration problems with high resolution, an optimal deconvolution method for systems with multiplicative noise is presented in the sense of linear minimumvariance. We develop the deconvolution algorithm in two steps. First, an optimal fixedinterval smoother of reversetime is constructed based on the reversedtime state space model for the systems. Then a onepass optimal deconvolution algorithm is presented by means of the state smoother. This deconvolution algorithm can avoid high storage requirements, and the simulation results for seismic signal processing are satisfactory.更多还原
