Development of a Radioastronomical Correlation Method for Measuring Mirror-Antenna Parameters

We consider the techniques and instrumentation developed at the Radiophysical Research Institute (NIRFI) for measuring mirror-antenna parameters using signals from extraterrestrial radio sources and geostationary satellites. The results of measuring the radiation patterns of several large-scale fully-rotatory radio telescopes in a wide dynamic range and of retrieving the amplitude and phase distributions on their apertures are presented.
