It is a well-established principle that cross-correlating seismic observations at different receiver locations can yield estimates of band-limited inter-receiver Green’s functions. This principle, known as function retrieval or interferometry, powerful technique transform noise into signals which enable remote interrogation and imaging the Earth’s subsurface. In practice it often necessary even...
