Abstract

An X-band radio astronomical receiving system for a prototype of radio telescope RT-4 has been developed. It includes a conical corrugated feed horn, a septum polarizer and low-noise amplifiers placed in a dewar, two frequency conversion units, a noise generator unit for amplitude calibration, a control and power supply system, and a cryo/vac system. The receiving system has been manufactured and mounted on the prototype of the RT-4 radio telescope at “Svetloe” observa55 tory. Radiometric measurements of the parameters of the RT-4 prototype were carried out. The possibility of joint VLBI observations of RT-4 and radio telescopes of Quasar VLBI network is confirmed by SEFD values obtained.

AB  - An X-band radio astronomical receiving system for a prototype of
radio telescope RT-4 has been developed. It includes a conical
corrugated feed horn, a septum polarizer and low-noise amplifiers
placed in a dewar, two frequency conversion units, a noise generator
unit for amplitude calibration, a control and power supply system,
and a cryo/vac system. The receiving system has been manufactured and
mounted on the prototype of the RT-4 radio telescope at “Svetloe”
observa55 tory. Radiometric measurements of the parameters of the
RT-4 prototype were carried out. The possibility of joint VLBI
observations of RT-4 and radio telescopes of Quasar VLBI network is
confirmed by SEFD values obtained.
