NEW APPROACHES IN OPTIMIZATION OF CALCULATION OF WAVE FIELDS DIRECTLY RELATED TO THE SELECTED TARGET AREA OF SEISMIC RESPONSE

The article describes the method of calculating the wave field of reflected waves of a certain type of re-reflection from localized target objects. A special feature of the method is the combination of the wave field continuation operator calculated by means of layer-by-layer recalculation based on the Kirchhoff integral and the finite-difference operator of reflected waves. Parameterization of the wave field continuation operator type is determined on the basis of the frame effective depth-velocity model. The research is carried out by Seismotech, Ltd under the grant support of "Skolkovo" Foundation.
