TL;DR: The Sardinia Radio Telescope (SRT) project as discussed by the authors is the result of a scientific and technical collaboration among three Structures of the Italian National Institute for Astrophysics (INAF): the Institute of Radio Astronomy of Bologna, the Cagliari Astronomy Observatory, and the Arcetri Astrophysical Observatory in Florence.
Proceedings ArticleDOI
Active surface system for the new Sardinia Radiotelescope
TL;DR: The Sardinia Radiotelescope (SRT) as discussed by the authors is a 64m shaped dish working up to 100 GHz by exploiting the active surface facility designed by the authors, which will overcome the effects of gravity deformations on the antenna gain and will also be used to re-shape in a parabolic form the primary mirror, in order to avoid large phase error contribution on the antennas gain for the highest frequencies placed on the primary focus.
Journal ArticleDOI
A Novel Application of the Active Surface of the Shaped Sardinia Radio Telescope for Primary-Focus Operations
TL;DR: In this paper, a modified primary reflector was proposed to increase the maximum frequency for primary-focus operation and also improve low-frequency multifeed capabilities of the 64m Sardinia Radio Telescope (SRT).

TL;DR: The Sardinia Radio Telescope (SRT) as mentioned in this paper is a radio telescope with a Gregorian optical configuration with a supplementary beam-waveguide (WG) which provides additional focal points.
