An interferometer consisting of one ground-based and one low-orbit space radio telescope (RACSAS-1) provides radio images of sources which are unambiguous and independent of model concepts using aperture-synthesis devices with adequate coverage of the spatial-frequency spectrum. An algorithm for numerical modeling of the process of covering the spatial-frequency spectrum was developed; it is shown that the two-element RACSAS-1 system is superior to multielement, ground-based, aperture-synthesis devices in covering the UV plane.
