Correction of the observed dynamic spectrums of solar radio emission

The World network of stations of radio service of the Sun is equipped with the one-type spectrographs CALLISTO for providing of continuous observations of the Sun during 24 hours. However the dynamic spectrums of the same radio burst are different at the stations of the World network. Apparently, spectrums are distorted by the uneven gain of receiving aerials which were not supplied together with a receiver and turned out to be different. The parameters of antenna, made in Laboratory of radio-astronomy of SRI CrAO are described in the article. For correct astrophysical interpretation of the registered information the method of exception of distortions of spectrum, brought by aerial, is developed and used at the station KRIM.
