Wave Method for Multiple Wave Suppression Without Knowledge of a Depth—Velocity Medium Model

摘要

A wave method for suppression of multiple waves that does not require knowledge of a depth-velocity medium model is developed. The method is constructed so as to completely suppress multiple waves in the case of a layer in a half-space. The efficiency of the method for arbitrary 3D plane-layered media is demonstrated both theoretically and numerically. Examples of the method application for real media showing a substantial decrease in the multiple wave amplitudes without distortion of the dynamics of useful reflections are given.
