| Abstract | 针对副反射面为非对称椭球面形式的多馈源、多频段天线反射体，需要对天线主反射面表面准确度、副反射面表面准确度及主反射面电轴、副反射面电轴和馈源系统中心轴的同轴度进行精确的测量和调整。应用数字工业摄影测量系统，以副反射面六杆联动机构的旋转中心轴为基准，对副反射面表面准确度进行精密测量和调整；在天线俯仰35°位置，以馈源系统中心轴为基准对主反射面表面准确度和副反射面姿态进行精密测量和调整。主反射面表面准确度优于±0.30 mm；副反射面表面准确度优于±0.11 mm；副反射面电轴和主反射面电轴的同轴度优于0.5 mm时，测试天线系统接收S频段和X频段信号的方向图，综合电气性能满足指标要求。 |
| Other Abstract | For the multi-feed and multi-frequency antenna reflector of asymmetric ellipsoidal plane, we need accurately measuring and adjusting the surface accuracy of the main reflector, the surface accuracy of the secondary reflector, and the axiality of the main reflection surface electric shaft, the second reflection surface electric shaft and the central axis of the feeder system. Using the digital industrial photogrammetry system, making precision measurement and adjustment of the surface accuracy of the secondary reflection surface; at the pre-adjusting position of 35 pitch angle, using the central axis of the feeder system to precision measure and adjust the surface accuracy and the attitude of the main reflection surface. When the surface accuracy of the main reflector is better than ±0.30 mm, the surface accuracy of the secondary reflector is better than ±0.11 mm, and the axiality of the secondary reflector and the main reflector is better than 0.5 mm, the antenna system received S and X frequency band signals of the direction map, comprehensive electrical performance to meet the requirements of the index. |
