Abstract. Obstacles in the ndimensional Euclidean space are considered
which are disjoint unions of finitely many convex bodies and
satisfy the condition (H) of M.Ikawa. Given such an obstacle K,
denote its exterior by Q, and let s(t,a,b) be the scattering
kernel related to the wave equation in RxQ with Dirichlet
boundary condition. It is shown that, among the obstacles in
consideration, K is completely determined if one knows the
singularities of s(.,a,b) for almost all pairs of unit vectors
(a,b).
