Abstract

This paper first describes three system specifications of the CSRH(Chinese Spectral Radioheliograph):angular resolution, time resolution, and frequency resolution(-technical specifications in radio astronomy)as these are relevant to the achievements of scientific goals.The paper subsequently gives three key technical specifications of the CSRH, sensitivity, dynamic range, and polarization isolation(common technical specifications of a receiver).We expounds emphatically the effects of the number, size, main specifications(efficiency, noise, and axis ratio)of antennas on the six specifications mentioned above.
- angular resolution,
- time resolution,
- frequency resolution,
- sensitivity,
- signal-to-noise ratio,
- dynamic range,
- fidelity,
- polarization isolation,
- axis ratio
