| Abstract: |
| A new assembly process technology is proposed, which applies the laser tracker and coordinate system conversion technology to the dual-reflector antenna assembly coaxiality and the relative distance of the reflector, etc. In the analysis, the SA software curve fitting function is used to obtain the origin of each reflecting surface coordinate system, the direction of the coordinate system, and the axis of the reflecting surface, etc.. And the deflection angle, coaxiality and relative distance information are calculated according to the coordinate system conversion principle to determine the adjustment direction. Sorting out the adjustment process provides a theoretical basis for designing an automatic adjustment equipment. |
| Key words: dual reflective antenna coordinate system conversion coaxiality relative distance laser tracker measurement |
