Ground-penetrating-radars (GPRs) are used for surveying underground-buried objects. In this paper, the authors proposed a method for reconstruction of upper surface contours in the vertical section of buried objects as a set of line elements. The line elements were obtained based on the condition that multiple ellipses provided by the different B-scope images satisfying a multiple root condition. The ellipses were defined by a constraint deduced from time-of-flight information in a B-scope image.

Furthermore, the effectiveness of the proposed method was confirmed through a field test.
