Radioheliograph array for the solar atmospheric dynamics

Studying the origin of solar activities, revealing the basic laws of solar activities and forecasting the violent solar eruptions are not only important problems in astronomy, but also the basis of protecting the near-Earth space environment and the many high-technology systems. In order to achieve this target, the radio telescope is required to have the capability to detect the solar element bursts and cover the huge source regions including magnetic energy release, propagations and evolutions. Based on these scientific objectives and the development of radio telescopes, in this paper, we proposed a new solar radio telescope array. It can be expanded step by step on the basis of the present WISER and the forthcoming meter-decimeter wavelength radioheliograph of Meridian II project. The maximum baseline of the proposed array will be extended to 30 km, and the spatial resolution will be improved to 0.2 ''. This array is able to detect the element burst procedure of different radio bursts in solar atmosphere plasma. The system schematic and the specifications of this array have been studies and designed preliminarily.
