The surface accuracy of a large parabolic antenna is an important indicator to evaluate the quality of the antenna. It not only directly affects the antenna’s aperture efficiency, thereby determining the shortest wavelength that the antenna can work, but also affects the main lobe width and side lobe structure of the antenna pattern. Microwave holography is an important method for parabolic antenna profile detection. In this article we adopt a new algorithm to adjust the panels for the large radio telescope with an active main reflector through the TM65 m antenna’s aperture phase profile. The panels of the TM65 m radio telescope is in a radial pattern with 14 rings. Each corner of the panel is fixed on the screw of the actuator to move up and down, and the adjacent corners of the four panels share an actuator. We use the method of plane fitting to calculate the adjustment value of every panel’s corner. But one actuator, which simultaneously controls the common corner of the adjacent panels, will have different adjustment values according to the different plane fitting equation based on adjacent panels. In this paper, the adjustment value of the adjacent panels’crosspoints are constrained to be equal to the constraint condition to calculate each actuator’s adjustment value of the TM65 m radio telescope. Through multiple adjustments and application of the new algorithms, the accuracy of the TM65 m antenna reflector profile has been improved from the original 0.28 mm to the current 0.19 mm.

大型抛物面天线的表面精度是评价天线质量的重要指标。它不仅直接影响天线的孔径效率，从而决定天线可以工作的最短波长，而且影响天线方向图的主瓣宽度和旁瓣结构。微波全息是抛物面天线轮廓检测的重要方法。在本文中，我们采用一种新算法，通过 TM65 m 天线的孔径相位剖面调整具有有源主反射面的大型射电望远镜的面板。TM65 m 射电望远镜的面板呈放射状，有 14 个环。面板的每个角都固定在执行器的螺杆上可以上下移动，四个面板的相邻角共用一个执行器。我们使用平面拟合的方法来计算每个面板角的调整值。但是一个执行器同时控制相邻面板的公共角，根据相邻面板不同的平面拟合方程，会有不同的调整值。本文将相邻面板交叉点的调整值约束为等于约束条件来计算TM65米射电望远镜各作动器的调整值。通过对新算法的多次调整和应用，TM65 m天线反射器轮廓的精度从原来的0.28 mm提高到现在的0.19 mm。根据相邻面板的不同平面拟合方程，会有不同的调整值。本文将相邻面板交叉点的调整值约束为等于约束条件来计算TM65米射电望远镜各作动器的调整值。通过对新算法的多次调整和应用，TM65 m天线反射器轮廓的精度从原来的0.28 mm提高到现在的0.19 mm。根据相邻面板的不同平面拟合方程，会有不同的调整值。本文将相邻面板交叉点的调整值约束为等于约束条件来计算TM65米射电望远镜各作动器的调整值。通过对新算法的多次调整和应用，TM65 m天线反射器轮廓的精度从原来的0.28 mm提高到现在的0.19 mm。
