Abstract:

The paper describes possibilities of tacheometers to control surface of reflector antennas. The accuracy of measurement by the triangular and direct methods has been estimated. The quality of manufacturing the surface of a parabolic reflector antenna has been tested. The way to find the coordinates of the top mirror and its focal point has been described. The graphs of level lines, which show deviations of tested surface of a reflector antenna from a perfect paraboloid, have been obtained.
