Array Configuration and Feed Design for CSRH

The Chinese Spectral Radioheliograph(CSRH) will be a solar-dedicated radio interferometric array that will be optimized to carry out imaging spectroscopy of the Sun,to produce high spatial resolution,high time resolution and high frequency resolution images of the Sun simultaneously in cm-dm wave range.Some work on array configuration and feed design for CSRH is described in this paper.On the array configuration,the four array design plans- "T","Y",irregular,and spiral configuration are discussed.It is argued that self-similar spiral geometries will be fit for CSRH.The scientific demands on feed design and ANSERLIN antenna used in our recent experiments are described.
