Signal delivery system in a subarray of Giant Ukrainian Radio Telescope

Abstract

Radio astronomy deals with the weakest signals received by a radio electronic device, and, as a result, it is very complicated problem to maintain appropriate SNR while transferring signal from the antenna output to receiver's input. In this paper, a system for delivering the radio astronomical signals from dipole terminals to ADC input of Giant Ukrainian Radio Telescope (GURT) is described. Examples of the received signal spectra in wide frequency range are shown.
