Abstract
A new method of double focusing is proposed for the tomography of inhomogeneous media which combines the approaches of active and passive coherent probing schemes. In combination with spatial filtering, this makes it possible to resolve inhomogeneities as small as half the operating wavelength in the probed medium. The satisfactory operation of the method is confirmed by the results of simulation modeling.
