Abstract :
It is important to have imaging - spectroscopy over centimetric-decimetric wave range to address fundamental processes in the solar eruptive phenomena. The Chinese Spectral Radioheliograph (CSRH) is a solar-dedicated interferometric array with frequency from 0.4GHz to 15 GHz. There are 40 antennas with 400MHz to 2 GHz, and 60 antennas with 2 GHz to 15 GHz in this array. CSRH-I and CSRH-II, which include antennas, receivers, and correlators have already been established. This paper introduced the system, progress and current status of CSRH.
