Aplicação do método de Kalman a dados geofísicos

Abstract

The Kalman filter is applied to the inverse filtefing or deconvolution problem. In this dissertation we applied the Kalman method, it is considered like a processament vition on time domain, to separet signal-noise within sonic perfil which is admited like no stationary stochastic process. In next work will survey deconvolution problem. The derivation given of the Kalman filter emphasizes the relationship between the Kalman and Wiener filter. This derivation is based on the modeling of randon processes as the output of linear systems excited by white noise. Ilustrative results indicate the applicability of these tchniques to a variety of geophysical data processing problems, for example the ideal well log teated here. The Kalman filter offters exploration geophysicists addtition insight into processing problem modeling and solution.
