3-CM RADIOHELIOGRAPHA 3-cm radioheliograph has been completed in July 1969 and ever since test observations have been made. The T-shaped antenna is composed of 32+16 dishes, and the resolution is 1.'6 and 2.'4 before and after smoothing in the direction near the zenith. The 'shutter speed' is about 20 minutes, and the map of circular polarization can be obtained as well ...

A NEW PROJECT OF 8-CM RADIOHELIOGRAPH
A NEW PROJECT OF 8-CM RADIOHELIOGRAPHAn 8-cm radio heliograph is planned by adding 17 N-S elements to the existing interferometer. The mapping speed will be one frame in 40 seconds. It is characterized by its ability of correcting phase errors by data processing.

Baseline measurement for Chinese spectral radioheliograph
2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014The Chinese Spectral Radioheliograph (CSRH) is a solar-dedicated synthesis aperture telescope. The maximum baseline length determines the high resolution of synthetic aperture. With its antenna array aligned in a shape of triple-spiral arms spread in an area of about 10 square kilometers.

The mark III Nan�ay radioheliograph The Radioheliograph Group
Solar Physics, 1983A north-south array has been added to the Mark II Nancay Radioheliograph (Radioheliograph Group, 1977). This instrument gives at 169 MHz two one-dimensional images of the Sun in the east-west and north-south directions including measurement of the circular polarization ratio. The main performances of this instrument are high space and time resolutions,

The Gauribidanur Radioheliograph
Solar Physics, 1998A 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

The Chinese Spectral Radioheliograph—CSRH
Earth, Moon, and Planets, 2008A new Chinese radioheliograph project (CSRH) at multiple frequencies in the decimetric to centimeter wave range with ∼100 antennas of 2–5 m is proposed. A prototype study of 2-element interferometer was tested for overall design. The site survey for the CSRH array is carried out and a radio quiet region in Inner Mongolia of China appears promising.
