Bayesian parametric separation applied to multicomponent seismic data

This letter addresses the parametric estimation of multicomponent seismic waves, The approach of parametric separation based on the maximum likelihood estimator (MLE) is introduced, and the a priori information is obtained by the downgoing waves in vertical seismic profile (VSP) data. First, we recall the MLE method, Then the Bayesian approach is introduced in the third section, and finally, we show on synthetic seismic data that the estimation of velocities of upgoing waves is improved.
