| Abstract: | Scanning frame is one of the key devices for testing,analyzing and finding the interference sources of a new CATR（ compact antenna test range） and for regularly calibrating a CATR which has been used. In this paper,a cylindrical support polar scanning frame is designed to simplify the scanning frame structure and improve the test efficiency. In order to achieve a rapid compensation,a flatness compensation device was developed. Experiments were then carried out. The results show that the flatness of the scanning frame with the compensation device can reach 0. 032 mm,which satisfies the requirements of CART calibration. |
