Inverse obstacle scattering with two scatterers. (English) Zbl 1026.35105
From the introduction: The authors consider the problem of determining the shape of an obstacle by the far field pattern of acoustic or electromagnetic scattered waves. Here they are interested in scattering by two obstacles D 1 and D 2 with D 1 D 2 and D 1 D 2 =. For a fixed obstacle D 2 , they show the uniqueness of the obstacle D 1 with the sound-soft condition on the boundary of D 1 .
