Finite-difference Modelling With Correction Filters In Variable Velocity
Manning, Peter M. (Dept. of Geology and Geophysics, University of Calgary) | Margrave, Gary F. (Dept. of Geology and Geophysics, University of Calgary)
In those papers we showed how a correction We call the third term on the right-hand side of Equation filter could compensate for finite-difference sampling (1) the acceleration term and we call the ratio of the two effects (with inherently stable conditions), and thereby squared sinc functions in the acceleration term the obtained results that matched analytic modelling.
