| Abstract: | Firstly, the detection model of the parabolic antenna is elaborated, the detection project using Laser Tracker is put forward. Then, a survey experiment to a small-diameter rotating parabolic antenna using Laser Tracker is conducted. Some 3D coordinate data of the antenna surface is collected and fitted by the parabolic model. And the focal distance of the parabolic is calculated using the fitting result. Lastly, to confirm the detection result, a contrast analysis between the calculated result and the designed value is conducted. |
