On the Relation between Seismic Interferometry and the Simultaneous-source Method

In seismic interferometry the response to a virtual source is created from responses to sequential transient or simultaneous noise sources. In the simultaneous-source method, overlapping responses to sources with small time delays are recorded. Seismic interferometry and the simultaneous-source method are related. In this paper we make this relation explicit by discussing deblending as a form of seismic interferometry by multidimensional deconvolution.
