The problem to be solved in this paper is to adjust the actuator at the lower end of the reflection panel, and then search to get the radial telescopic of the adjustment actuator, so that the gap between the working paraboloid formed by the reflection panel and the ideal paraboloid can be minimized, and the reflection panel can achieve an ideal paraboloid with the best receiving effect. When the object is at the azimuth angle of 0° and the elevation angle of 90°, the plane rectangular coordinate system is established in the XOZ plane, and then the equation of the working parabola is established in the coordinate system. The design algorithm searches for the value of the actuator radial telescopic, and the equation of the parabola is obtained. Finally, the parabola is rotated along the Z axis to obtain the final ideal parabola.
