Abstract


A method of measurements of radio source flux density used
with the decameter wavelength interferometer network URAN.
The procedure of antenna gain calibration of radio telescopes by
using the emission of powerful radio sources and radio astronomy
technique is suggested. An experimental dependence of the
measured flux on scintillation index is used to account for spatial
averaging by large arrays of phase fluctuations of the field which
are caused by the influence of the ionosphere.
