Meter to Decameter Wave Spectral Radio Heliograph

To detect the solar intense activities including the solar flare, Coronal Mass Emission(CME), interplanetary shock wave, non-thermal particles, solar winds, etc. in the interplanetary space, a meter-decameter wave spectral radio heliograph has been proposed as one of the main instruments for Meridian II project in China. It can achieve the solar imaging at the frequency range from meter to decameter with the capability of high-temporal, high-spectral and high-spatial resolutions. To serve the space weather study, this radio heliograph can monitor fully the disturbance sources produced by the solar radio bursts in the interplanetary space.
