摘要：

For many years, ground-based radio observations of the Sun have proceeded in two directions: i) high resolution imaging at a few discrete wavelengths; ii) spectroscopy with limited or no spatial resolution at centimeter, decimeter, and meter wavelengths. Full exploitation of the radio spectrum to measure coronal magnetic fields in both quiescent active regions and flares, to probe the thermal structure of the solar atmosphere, and to study energy release and particle energization in transient events, requires a solar-dedicated, frequency-agile solar radiotelescope, capable of high-time, -spatial, and -spectral resolution imaging spectroscopy. In this paper pre summarize the science program and instrument requirements for such a telescope, and present a strawman interferometric array composed of many (> 40), small (2 m) antenna elements, each equipped with a frequency-agile receiver operating over the range 1-26.5 GHz.
