Abstract

Abstract

A mathematical model was established to optimize the acceptance ratio of the feed cabin of China's Eye of Heaven, the Five-hundred-meter Aperture Spherical Telescope (FAST), and the ideal parabolic equation of the reflector of FAST system was obtained. The adjustment scheme of the main cable node of the system was given based on the genetic algorithm. The numerical simulation shows that the reception ratio of the feed cabin is 61.43% when the observed celestial body's azimuth is 36.795° and elevation is 78.169°. The acceptance ratio of the feed cabin is about 55.97 percentage points higher than the base sphere.
