Daylight seismic imaging from a buried point source

Abstract

We applied acoustic daylight imaging technique to one buried point source problem. This method can synthesize shot records of the same number as receivers, with only one actual source explosion. The reflection response can be obtained by the cross‐correlation of the transmission responses. In this paper, we show a numerical simulation and then we apply this method to the field data observed by an explosive response. We obtained subsurface images clear enough to estimate underground structures, and the obtained subsurface image is in good agreement with the section acquired by a conventional reflection survey.
