Paper Abstract

As the requirement of satellite antenna’s planar near-field test, the scanning plane, the air-bearing based platform and the satellite antenna should be measured and adjusted with high precision. In order to improve the measurement accuracy and efficiency for large scale objects, a new measurement method is proposed based on laser radar. Target ball measurement, scanning measurement and single point measurement are respectively used to measure the scanning plane, the air-bearing based platform and the satellite antenna. The working principle, automatic measurement method and measurement error are described in detail. The experimental results show that the measurement error is less than 0.1mm for 3D point coordinate and 10” for attitude angle. Compared with traditional theodolite measurement method, this method can realize automatic measurement with higher precision and efficiency.
