Abstract
Interferometry is a method of redatuming physical sources to receiver locations. Under idealized assumptions stacking the cross correlogram of the two common receiver gathers yields a bandlimited
Green's function between the receivers. Geometrically this process
amounts to isolating a physical source, which generates a path containing both receivers, and canceling the common part. In this paper, we show that in order to recover the travel time between two
receivers, one could creatively use rays from more than one physical
source. With this approach redatuming is possible even in situations
where the conventional interferometry fails.
