Abstract

Holographic measurement is an important method to detect deformation of a radio-antenna surface from the parabolic shape. A key element of holographic measurement is a data-calibration software package. To serve the plan of transforming the 25m radio antenna in the Nanshan Station of the Xinjiang Astronomical Observatory (XAO), we study contributions of different sources to measurement errors of antenna holography. We further develop a software package for data calibration of holographic measurement by using a Linux operating system as the development platform and the Python as the development language. Our package has several merits. First, it can evaluate reasonableness of errors and filter out data records of excessive errors. This provides convenience for users. Second, it has standardized interfaces that are rather easily to be embedded into the antenna control software. Third, its visual interface is user friendly and can display results visually. Our debugging of the package has shown that it is highly practical and effective. The package not only can have crucial applications in the reconstruction of the 25m antenna, but also can be used to provide technical predictions for the design of the XAO 110m radio telescope.
