ABSTRACT
Aiming at the problem of determining the ideal paraboloid in FAST, this paper obtains the variation model of the working paraboloid based on the objective programming model, ergodic method, linear fitting, and spatial geometry knowledge. In this paper, the ideal paraboloid is as close as possible to the spherical reference surface, and the variation range of the distance between adjacent nodes and the radial expansion and contraction range of the actuator are used as constraints and target optimization model. Moreover, find the ideal paraboloid when the celestial body S to be observed is located at
