    Stepwise Multiple Elimination Using Linear Transforms

    SMELT™ is an innovative approach to multiple attenuation, it can serve as an alternative to Radon or 2D SRME and as a complement to 3D SRME. Applied in the CMP domain, it creates a multiple model for subtraction by successive applications of a narrow forward-inverse linear tau-p transform is applied in discrete steps from water to a peg-leg velocity. Since multiples are flattened prior to transformation the process is unaffected by aliasing.
