Abstract :
Imaging spectroscopy over the cm- and dm-wavelength ranges is important for solar physics. A radio heliograph with high temporal, spectral and spatial resolutions has been proposed and we describe briefly the concept for this instrument. Some pre-studies have been carried out which show perspectives of the project.
