Sardinia Radio Telescope structural behavior under solar thermal load [PDF]

Structures, 2022
Sardinia Radio Telescope (SRT) with its 64 m diameter primary mirror is a modern radio-astronomic facility. Its large dimensions allow to reach high performances, but, at the same time, make the antenna sensitive to deformations caused by environmental factors such as gravity, wind and temperature changes.

Correction of the temperature effect in calibration of a solar radio telescope

Research in Astronomy and Astrophysics, 2021
Abstract This work analyzes the annual fluctuation of the observation data of the Mingantu Solar radio Telescope (MST) in S, C and X bands. It is found that the data vary with local air temperature as the logarithmic attenuation of equipment increases with temperature and frequency.

A New 6–15 GHz Solar Radio Observation System

The Astrophysical Journal Supplement Series, 2023
In this study, we have developed a centimeter-band solar radio telescope covering the 6–15 GHz frequency band. The radio telescope has the outstanding advantages of a large instantaneous sampling bandwidth and wide frequency coverage.

Radiosolariz Solar Radio Telescope Short Monopole Antenna

Proceedings of the Bulgarian Academy of Sciences
The current paper explores the possibility of implementing a shortened monopole antenna for the purposes of radio reception of broadband radio emission from the Sun in the low portion of the very high frequency (VHF) radio band. The frequency range of interest is the lowest band starting from the top high frequency (HF) spectrum near 20~MHz and ...

Imaging of the Solar Atmosphere by the Siberian Solar Radio Telescope at 5.7 GHz with an Enhanced Dynamic Range [PDF]

Publications of the Astronomical Society of Japan, 2013
Abstract The Siberian Solar Radio Telescope (SSRT) is a solar-dedicated directly-imaging interferometer observing the Sun at 5.7 GHz. SSRT has operated in the two-dimensional mode since 1996. The imaging principle of SSRT restricts its opportunities in observations of very bright flare sources, while it is possible to use ‘dirty’ images ...
