摘要

Based on the optical interferometric principle, a seismic imaging method which use seismic wave to replace optical wave, named seismic interferometric imaging method is presented. This method needn’t to pick up first arrival, and can use any array detectors as the observation system. A two-dimensional time delay record from a subsurface source is simulated, and a C-based positioning procedure for seismic source is established, then use this method to invert. The results indicate that the method is feasible and high in location accuracy.
