Abstract.
The paper suggests ways to control the characteristics of the radio
telescope RATAN-600 using the geostationary satellites. The results of the
measurement of two-dimensional antenna patterns and focal spots, the reflecting
elements and groups of elements of the radio telescope efficiency
(contribution) are presented, as well as the comparison of the measured
characteristics with the model. A method for estimating the parameters of the
antenna efficiency on measured, calculated and approximated characteristics is
considered, estimates of the achievable accuracy in a feasible measurement
region are given. The results show highly informative and effective method for
monitoring of the radio telescope performance using the geostationary
satellites.
Key words:
radio telescope, reflecting elements, monitoring and modeling of antenna
characteristics, geostationary satellites.
