摘要

射电天文学处理的是无线电电子设备接收到的最弱信号，因此，在将信号从天线输出传输到接收机输入时保持适当的信噪比是一个非常复杂的问题。介绍了一种从偶极子终端向乌克兰巨型射电望远镜(GURT) ADC输入端传输射电天文信号的系统。给出了宽频率范围内接收信号频谱的实例。

Signal delivery system in a subarray of Giant Ukrainian Radio Telescope

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.
