In this paper, the adjustment strategy and signal acquisition ability of the active reflection panel of 500m aperture spherical radio telescope are studied. Firstly, based on the fact that the ideal paraboloid is rotating, the geometric model is established, the geometric elements of the parabola are solved combined with the geometric properties of the parabola, and the ideal paraboloid equation is obtained. The focal distance is 280.053m, and the vertex coordinates are (0,0,-300.440). Then, rotate the original coordinate system and establish a new object coordinate system so that the measured object is located in a similar special position. The parabolic focal distance is 280.053m, and the vertex coordinates are (-49.327,-36.894,- 294.058). Finally, the programming model is established, the expansion and contraction of the relevant actuator are taken as the decision variable, and the sum of the absolute values of the deviation between the main cable node of the reflective panel and the ideal paraboloid is taken as the objective function. With the help of a genetic algorithm, the programming model can be solved to obtain the expansion and contraction of the relevant actuator, and then the coordinates of the main cable nodes of the paraboloid participating in the adjustment in the basic coordinate system can be solved according to the principle of coordinate system transformation.
