Ultrabroad-band tomography of remote objects

A method for restoring the images of remote objects with the system’s instrument function in ultrabroad-band (UBB) pulse sounding is considered. The system is a synthetic-aperture radar combined with a parabolic reflector. The aperture was synthesized via UBB scanning with a transceiver over the near-focus plane of a parabolic rereflector. Such a scheme allows the boundary of the maximum offset of a sounded object to be displaced at a distance equal to 2–3 diameters of the parabolic reflector. An additional advantage of the system that contains a parabolic reflector (rereflector) consists in the possibility of focusing radiation to a specified remote spatial region. In support of the validity of this method, we represent the results of numerical and physical modeling.
