| Abstract(in English) | The estimation method of not only reflector position but also propagation constants is proposed using combination of tomography method and MUSIC algorithm. The propagation constant is iteratively obtained with minimization of the noise eigenvalue in which the direct wave is subtracted. The reflector position is estimated with the noise eigenvector. The validity of this method is demonstrated through FDTD simulations. It is found that the propagation constant and reflector position can be estimated in the inhomogeneous medium which has the width of refractive index and attenuation constant of 0.72 and 1.8, respectively. |
