• In this paper, the structure of the ideal paraboloid and the influence of various factors of the regulating system on signal reception are studied. Firstly, the selection range of the focal point of the ideal parabola was determined as an interval near the feed cabin, which was based on the properties of the focusing parallel ray of the parabola and the received region as the central disk. At the same time, considering the adjusting factors of the reflecting panel, the endpoint of the ideal parabola was given as the constraint interval, and the optimization model was established. Then the optimal solution and the ideal parabolic equation are obtained by the two-dimensional grid search algorithm. Watch the stars due to the Angle of the change. However, the ideal parabolic structure remains the same so that the use of the 3-d coordinate rotation formula will get the corresponding front ideal paraboloidal rotation angles of the parabolic equation. The ideal center to lighting area is the center, center with the endpoint of length to the radius to form a sphere, The main cable node in the sphere is the node that needs to be adjusted in the working state. Then, considering the actuator expansion of each adjusting node and 2076 variables of cable deflection Angle as optimization variables, the optimization model was established with the main cable node as close to the ideal parabola as possible after adjusting and the distance between nodes as small as possible as the objective function, and the differential evolution algorithm was used to obtain the optimal solution.
