Abstract

The results of experimental studies of noise temperatures of the receiver system (NT RS) of radio telescope RT-13 of two-elements radio interferometer with syperlong base in the frequency ranges S (2,2–2,6 GHz), X (7,0–9,5 GHz) and Ka (28–34 GHz) are shown.. The experimental results has been obtained with use of wide-aperture low-temperature generators noise. Limits of permissible error of measurement NT RS (P=0,95) of RT-13 were not more than 3,5 К.
