| Abstract: | In this paper, we first discuss the direct scattering problem for a cylindrical homogeneous clastic tube with a geometrical method, and then study the inverse problem. The heuristics of B-F procedure (Best-First search strategy) is used. The inner radius, outer radius, sound velocitics of the tube and sound velocity of the internal medium are obtained with this heuristics. |
