RHESSI and Radio Imaging Observations of Microflares E2.3-0011-04

, 2005
We present the analysis of five microflares, three observed simultaneously by RHESSI in hard X-rays and Nobeyama RadioHeliograph (NoRH) in microwaves (17 GHz) and two observed by RHESSI and Nancay RadioHeliograph (NRH) at metric wavelengths (150-450 MHz).

Large scale structure of the solar corona in the declining phase of the solar cycle

, 1995
Maps of the corona, obtained at meter wavelengths with the Nançay Radioheliograph (France), are used to study, on the disk, the radio counterpart of the coronal plasma sheet observed in K-corona on the limb.

Evolution of the coronal plasma sheet from cycle maximum to cycle minimum observed at meter wavelengths

, 1995
The Nançay Radioheliograph provides maps of the quiet solar corona around 160 MHz. In addition to coronal holes, localized emission sources and quiet sun, an unresolved component can be detected on the disk.

High speed digital synchronized system for antenna array such as Nançay Radioheliograph

, 2018
Le Radiohéliographe de Nançay est le seul instrument dédié à l'imagerie du soleil en ondes décimétriques-métriques. Il fonctionne sur le principe de l'interférométrie, en utilisant 47 antennes essentiellement réparties sur des axes est-ouest (3,2 km) et ...

A NEW PROJECT OF 8-CM RADIOHELIOGRAPH

A NEW PROJECT OF 8-CM RADIOHELIOGRAPH
An 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), 2014
The 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.
