A study of techniques for measuring ultra-low-sidelobe antennas by the near-field method

This paper presents some key techniques for measuring ultra low sidelobe antennas by near field scanning, and discusses various error sources that directly affect the measurement accuracy. Emphasis is placed on the error analysis and correction method for these error sources, and the suggestions for theoretical analysis and practical engineering methods are proposed. Computer simulations and experiments are performed in teh near field system developed at Xidian University. The results obtained show that the realization of ultra low sidelobe antenna measurement by near field scanning is possible only if the hardware and software accuracy of the test system are further enhanced and the error diagnosis and correction are rigorously made.
