A new possibility of two-dimensional image creation for variable-aperture antennas is considered. An image correlation technique is proposed to recover two-dimensional images in a single passage of the source through the two-dimensional radiation pattern of the RATAN-600 radio telescope in the incoherent irradiation mode. High sensitivity of instantaneous mapping can be reached in spectrographic observations by both integration in the frequency band and long-term object tracking.
