Abstract
It is possible to estimate the travel time or even the full Green´s function between two passive sensors from the cross correlation of recorded signal amplitudes generated by ambient noise sources. Using the stationary phase method we show that it is possible to image reflectors buried in a smoothly varying medium by migrating the cross correlations of the noise signals.
