A wave method for multiple waves suppression for any complex subsurface geometries

A wave method for suppression of multiple waves that does not require knowledge of a depth-velocity medium model has been developed. The method is constructed so as to completely suppress multiple waves in the case of a layer in a half-space. This is the principle distinction from the existing methods. In particular, this leads to the fact that no a priori data about the medium structure is required and the depth-velocity medium model is considered unknown. The efficiency of the method for arbitrary 3D plane-layered media is demonstrated both theoretically and numerically. Examples of the method application to real media showing a substantial decrease in the multiple wave amplitudes without distortion of the dynamics of useful reflections are given.
