ABSTRACT

Exact Green's function representations for seismic inter-ferometry are based on the assumption that the receivers used in the correlation process are surrounded by a closed surface of sources. We investigate two situations for which this condition is not fulfilled: sources only in the subsurface, as in passive seismics, and sources only at the surface, as in exploration seismics. We show that in both cases the full Green's function, including primary and multiply scattered waves, can be reconstructed.
