Backward Propagation

A method is proposed for imaging of scattering heterogeneities in continuous media on the basis of numerical modeling of forward and backward wave propagation. It is shown that the combination of a solution for backward propagation of waves and direct wave propagation allows us to visualize scattering heterogeneities. The results of numerical simulation are presented.
