EMC study in chinese spectral radioheliograph

2015 1st URSI Atlantic Radio Science Conference (URSI AT-RASC), 2015
There are always the Electromagnetic compatibility (EMC) problems where the electromagnetic phenomenon exists. EMC is an inescapable problem in radio astronomy and also common problem for radio astronomical telescopes.

The mark II Nan�ay radioheliograph

Solar Physics, 1977
We describe the new Nancay Radioheliograph (version II) which is a multicorrelator system. The main characteristics of this instrument are high space and time resolutions and flexible on-line data processing. At present it produces one-dimensional images at 169 MHz. This instrument is mainly intended for solar observations.

Evaluation of the Imaging Performance of the Nobeyama Radioheliograph

Publications of the Astronomical Society of Japan, 1994
Abstract The Nobeyama Radioheliograph is a radio interferometer dedicated to solar observations at 17 GHz. Its imaging performance is concisely described on the basis of the correlator outputs. Antenna-based errors are removed by a self-calibration method.

Sympathetic Events As Observed with the Nobeyama Radioheliograph

Геомагнетизм и аэрономия / Geomagnetism and Aeronomy
Sympathetic phenomena on the Sun are events that occur at short time intervals in active regions located at large distances from each other. The presence of such events indicates that even very distant active regions may be connected physically to each other.

A summary of three-year observations with the Nobeyama Radioheliograph

AIP Conference Proceedings, 1996
The Nobeyama Radioheliograph was completed in two years by 1992 March. It has been put into regular observations in late June 1992 for eight hours a day from 23h UT to 07h UT. It has caught some part of maximum activities of the Sun, but not so large as the flares in 1991 June.
