Abstract :
New methods of the coherent tomography are proposed for layered media with embedded 3D inhomogeneous structures. The retrieval of the structure of media parameters is based on the solution of 3D integral equations of the perturbation theory that are reduced to convolution equations with respect to lateral co-ordinates using the lateral 2D Fourier transform and the plane wavespsila decomposition of Green functions. Results of numerical simulation are presented.
