| Abstract: | This paper first shows the Radon transform corresponding to some seismic data acquisition systems and mathematic models of forestack seismic records. Based on the analysis of the relationship between the generalized Radon transform and the forestack seismic records, the mathematical implication of forestack data processing, such a svelocity spectrum analysis, normal moveout, filtering and stacking, are discussed for display the potential application of the generalized Radon transform. We finally show a method of removing multiples together with some numerical examples. |
