Abstract(in English) | We can find the position of rebar into concrete structure by using radar method. However as the relative permittivity of concrete is unknown, the accurate estimation of the depth of rebar is very difficult. Until now, we supposed that the permittivity of concrete is uniform and proposed simultaneous estimation of the permittivity of the concrete and the depth of the rebar. In generally, the permittivity of concrete is inhomogeneous. In this paper, we propose the estimation of rebar using the synthesis aperture processing considering the permittivity distribution of concrete. By numerical simulations, the effectiveness of proposed method is shown. Also, reflection waves from rebar into the inhomogeneous concrete structure are obtained in numerical calculations using the two-dimensional FDTD and the permittivity distribution is used the measured one of self-made concrete. |
