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 ...

A Proposed Correlator Backend for the Culgoora Radioheliograph

Publications of the Astronomical Society of Australia, 1979
The Culgoora radioheliograph was designed in the early 1960s and commissioned in 1967. Since then there have been dramatic increases in the speed and versatility of digital integrated-circuit devices, and also a marked fall in their cost. It is now possible to replace the original signal processing electronics with equipment, based on modern digital ...

Radioheliographs and Radio Reflectors in Solar Plasma Studies

Astrophysical Bulletin, 2019
The paper covers characteristics of big interferometers and reflecting radio telescopes intended for the studies of the solar atmosphere radiation. Solar radio interferometers (radioheliographs) have proven to be more cost-effective than single dish radio telescopes, since using the aperture synthesis allows for fast imaging of the Sun and its active ...

Solar Image Processing with the Clark Lake Radioheliograph

1985
The Clark Lake Teepee Tee radio telescope is located near Borrego Springs, California and is owned by the University of Maryland. The telescope has been operating since 1981 in different stages of software and hardware development, and is used for both sidereal and solar studies.

First results from the Clark Lake Multifrequency Radioheliograph

Solar Physics, 1983
The characteristics of the Clark Lake Multifrequency Radioheliograph, which is presently being used for solar research in the frequency range 20-125 MHz, are examined and several solar maps obtained with this instrument are presented. Two-dimensional images of the sun's corona at several frequencies within this range are examined, which were obtained ...
