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 ...

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,

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 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.
