Since there exisits inherent correspondence between the residual static equation and Radon Transform, each term in statics can be extracted via Radon Transform after residual time-shifts are converted into the corresponding Radon Transform data. This paper will discuss the theory of applying Radon Transform to 3-D residual statics and put the method to trial on a theoretical model. It's feasibility is finally confirmed via the comparsion of it's result to that from the conventional grneralized linear residu...
