Paper Abstract

In order to accurately position the nodes of a SAR(synthetic aperture radar), a special assemble workbench is designed and a laser tracker named LTS-1100 from the API is used to measure it. The two stations layout of laser tracker along the lengthways center line of the workbench are adopted. The six common points used when the laser tracker moving from one station to the other are selected based on the stability experiment under the working environment. The laser tracker measures the positions of all the points real time and directs their adjustments. The distance error of the points from the ideal on the workbench is less than ±0.105mm. The close range photogrammetric method is then used to measure the nodes position of the SAR antenna assembled on the workbench. The result indicates the coincidence with that obtained by the laser tracker.
