ABSTRACT

This paper studies the development of active reflector technology in radio astronomy and its market prospect. Firstly, the active reflector technology of FAST is introduced, and its potential in improving the sensitivity and resolution of radio telescopes is discussed. Then the specific application of active reflector technology in radio band celestial observation is analyzed in detail, including the advantages and challenges of beamforming, phase correction and interferometry. The prospects of active reflector technology in the market are further discussed, especially for potential applications in commercial radio astronomy and satellite communications. Finally, the future development direction and possible research directions of active reflector technology are prospected, and its importance and market demand in promoting the technical progress of radio astronomy and solving key scientific problems are emphasized.
