Abstract: The measurement scanner is one of the key equipments for measurement system of the compact range.Scan planeness of scanner is one of the key indicators that affect measurement accuracy. In this paper, a real-time compen?sation for planeness of the measurement scanner is designed, for a large polar scanner with a scanning area of φ6m. The real-time compensation system can detect the positional deviation of the scan plane relative to the reference plane in real time and the servo compensation agency completes the compensation. The test results show that the real-time compensation system can accurately and quickly complete the planeness compensation. Compared with the semi-real-time compensation method, it has a higher efficiency and accuracy. Presently, the real-time compensation system has been successfully applied to the calibration of compact range.
