Abstract

Measurement results of the parameters of the RT-13 radio telescopes of the “Quasar” VLBI network in S/X/Ka bands are presented in this paper. The receiver noise temperature and calibration signals are measured by special wide-aperture noise load. Load is installed at the receiver feed and cooled by liquid nitrogen. The calculated and measured system noise temperatures are compared. Focusing and directional pattern measurements are performed by point cosmic radio sources, differing for S/X/Ka bands. SEFD and antenna efficiency are measured by reference cosmic radio source CAS A. The dependences of the system noise temperature, SEFD, antenna efficiency from the antenna elevation angle are obtained.
