Abstract :
We proposed a synthetic aperture GPR (Ground Penetration Radar) for buried flat-plates. The geometrical conditions of the flat-plates, i.e., the length, the inclination angles, the horizontal positions, and the buried depth are estimated by using a nonlinear least-squares method: the geometrical model-calculated propagation times are fit to the observed ones at all the antenna positions. We carried out some survey experiments to inspect a metallic plate being buried in soil medium, and, furthermore, compared the proposed algorithm with a visual observation-based method. As a result, we confirmed the effectiveness of the proposed algorithm.
