摘要

The Chinese Spectral Radioheliograph (CSRH) is a solar-dedicated interferometric array with a frequency range from 400MHz to 15 GHz. There are 40 4.5m antennas with 400MHz to 2 GHz, and 60 2m antennas with 2 GHz to 15 GHz in this telescope. CSRH is under construction at Mingantu station, which is about 400 km away from Beijing in China. Now, CSRH-I, which includes an antenna, a receiver, and a correlator in the decimetric wave range, has already been established. CSRH-II is under construction and will be completed by the end of this year. This paper introduces the whole system of CSRH-I briefly, and presents delay measurements, polarization calibration, and some other results of calibration and data processing for CSRH-I.
