Wide-Aperture, Low-Temperature Noise Generators for Calibration of the Radio Telescopes of Two-Element Radio Interferometer with Very Long Baseline

详细

A complex of wide-aperture, low-temperature noise generators developed and certified at the All-Russia Research Institute of Physicotechnical and Radio Measurements (VNIIFTRI) and intended for metrological assurance of the RT-13 radio telescopes of a two-element radio interferometer with very long baseline is described. The results of studies and calibration of standard and working wide-aperture, low-temperature noise generators needed for metrological assurance of instruments used in the measurement of radio brightness and noise temperatures in the microwave region of the spectrum from 2 to 40 GHz are presented.
