Publikováno v: 2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS).

We present the status of the Sardinia Radio Telescope (SRT) and its forthcoming update planned in the next few years. The post-process scenario of the upgraded infrastructure will allow the national and international scientific community to use the S

A high temperature superconductor notch filter for the Sardinia Radio Telescope

Autor: Dario Panella, Luca Cresci, Pietro Bolli, S. Mariotti, Frederick Huang

A High Temperature Superconductor filter operating in the C-band between 4200 and 5600 MHz has been developed for one of the radio astronomical receivers of the Sardinia Radio Telescope. The motivation was to attenuate an interference from a weather

More than half a century ago, in 1952, Giuliano Toraldo di Francia suggested that the resolving power of an optical instrument could be improved using a filter consisting of finite-width concentric coronae of different amplitude and phase transmittan
