## ABSTRACT
It can be shown that for a 1-D Earth model illuminated by random plane waves
from below, the cross-correlation of noise traces recorded at two points on the
surface is the same as what would be recorded if one location contained a
shot and the other a receiver. If this is true for real data, it could
provide a way of building `pseudo-reflection seismograms' from background
noise, which could then be processed and used for imaging.
This conjecture is tested on synthetic data from simple
1-D and point diffractor models,
and in all cases, the kinematics of observed events
appear to be correct.
The signal to noise ratio was found to increase as , where |
