Recovering Of Scattering Objects By Means Of Focusing Transformation Of Seismic Multioffset Data

Focusing transformations of multi-offset data is a powerful tool to study complex<br>media (trapp intrusion, complicated upper part of a cross-section, thin interior layers<br>and so on). Its main advantage is a possibility to perform focusing simultaneously<br>with respect to sources and geophones and on this base to strength spatial structures<br>with specific disposition. But the choice of their optimal parameters (number of<br>sources and geophones, distance between centers of their bases, a degree of nonsymmetry<br>and so on) for a specific geological situation is rather bulky procedure.<br>The method to perform this choice by means of synthetic data gained with the<br>help of finite difference simulation of wave propagation for realistic models is proposed<br>and tested. The necessary condition to provide efficiency of the method is to<br>take into account all specific features of the specific process of wave propagation.
