The Nobeyama radioheliograph

Proceedings of the IEEE, 1994
A new 17-GHz radio interferometer dedicated for solar observations was constructed in two years at Nobeyama, Nagano. It consists of eighty-four 80-cm-diameter antennas arranged in a tee-shaped array extending 490 m in east-west and 220 m in north-south directions.

The Gauribidanur Radioheliograph

Solar Physics, 1998
A new radio heliograph for obtaining two-dimensional images of the solar corona sequentially at many frequencies in the range 40–150 MHz has been built by the Indian Institute of Astrophysics at the Gauribidanur Radio Observatory (lat. 13°36′12″ N and long. 77°27′07″ E) about 100 km north of Bangalore, India. This paper describes various aspects of the

Plans for a new radioheliograph in Belgium

Solar Physics, 1992
The existence of “spikes” with very short time scales (1 to 10 ms) in the decimetric radio spectrum emphasizes the necessity of building radio instruments with very high time resolution. Therefore, we are planning to build a multi-frequency decimetric radioheliograph at the radioastronomical station of the Observatoire Royal de Belgique (Humain ...

The study of phase closer of Mingantu Spectral Radioheliograph

2017 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2017
Mingantu Spectral Radioheliograph (MUSER) is a key instrument supported by the Chinese National Major Scientific Equipment R&D Project. It is a new generation solar-dedicated telescope and will play an important role in solar physics, space weather prediction, and even space missions.

Use of the Culgoora Radioheliograph for the Generation of Diffraction Patterns

Applied Optics, 1971
A series of diffraction patterns produced with the electronic imaging system of the Culgoora radioheliograph is presented. These patterns serve both to illustrate the quality of this type of imaging system and to demonstrate the advantage, in special circumstances, of constructing a radio-frequency simulation of an optical imaging device.

A proposed millimeter radioheliograph

Proceedings of the IEEE, 1973
A radio telescope capable of two-dimensional mapping of the sun at a millimeter wavelength with resolution of a few seconds of arc would add greatly to our knowledge of the sun and solar flares. A design which promises to make such an instrument possible is being studied at present.
