A simulation of imaging capabilities for the Chinese Spectral Radioheliograph

This work applied Chinese Spectral Radioheliograph(CSRH) to simulate the quiet Sun to produce the radio image. Then, we simulate a point source, and make all antennas have a typical phase error(5°) to calculate the dynamic range. It is found that the dynamic range agrees with the theoretical value. The image processing and simulated results are presented. © International Astronomical Union 2013.
