The polarization degree measurement of the original solar radio emission

The Chinese Spectral Radioheliograph (CSRH) is an aperture-synthesis telescope observing the Sun in ultra wide bandwidth. The relatively calm solar atmosphere can be violently disrupted by powerful explosions, filling the solar system with radio waves, X-rays, and gamma rays, another solar explosions, called Coronal Mass Ejections, throw billions of tons of corona gases into interplanetary space, and creating powerful gusts in the solar wind. Now, we begun to understand the detailed causes of Sun´s explosive outburst and predict exactly when they will occur. CSRH will give solar radio images to explore these mysteries. This instrument contains two arrays CSRH-I and CSRH-II from 0.4 to 15GHz. CSRH-II array covers frequencies from 2 to 15GHz.
