Fig. 2From: Retrieval of long-wave tsunami Green’s function from the cross-correlation of continuous ocean waves excited by far-field random noise sources on the basis of a first-order Born approximationConfiguration of two points x A and x B , and a scatterer located at y j . When a source is located at x B , a wave radiated from the source propagates to the scatterer y j and is scattered with an angle of Ψ j . The scattered wave then arrives at x A .Back to article page
