  Recently, several new solar radio telescopes have been put into operation and
provided spectral-imaging observations with much higher resolutions in
decimeter (dm) and centimeter (cm) wavelengths. These telescopes include the
Mingantu Spectral Radioheliograph (MUSER, at frequencies of 0.4 - 15 GHz), the
Expanded Owens Valley Solar Array (EOVSA, at frequencies of 1 - 18 GHz), and
the Siberian Radio Heliograph (SRH, at frequencies of 3 - 24 GHz). These
observations offer unprecedented opportunities to study solar physics and space
weather, especially to diagnose the coronal magnetic fields, reveal the basic
nature of solar eruptions and the related non-thermal energy release, particle
accelerations and propagation, and the related emission mechanisms. These
results might be the important input to the space weather modeling for
predicting the occurrence of disastrous powerful space weather events. In order
to provide meaningful reference for other solar physicists and space weather
researchers, this paper mainly focus on discussing the potential scientific
problems of solar radio spectral-imaging observations in dm-cm wavelengths and
its possible applications in the field of space weather. These results will
provide a helpful reference for colleagues to make full use of the latest and
future observation data obtained from the above solar radio telescopes.
