The study presents the results of constructing radio images by method of multistatical holography based on the electrodynamic models of three-dimensional objects. The initial data for simulation were the values of the complex amplitude of the field, which were recorded via the elements of the receiving antenna array. We examined the method of rear projections and applied it to electrodynamics models. It allows us to restore the shape and size of the object in cross section and to define its boundaries longitudinally. The full spatial image of the object can be recovered. The increase in the number of frequencies leads to the increase in the quality of the restored image both in the longitudinal and in the cross sections.
