In this paper, some key technologies involved in near field test of ultra-low sidelobe antenna and various kinds of error sources that directly affect the accuracy of test calculation are discussed. In particular, the methods of error compensation are discussed comprehensively, And project practical value.Based on the computer simulation and experimental research on the near field test system developed by Xi’an University of Electronic Science and Technology, the results show that as long as the hardware and software of the test system can be further improved in accuracy and subjected to rigorous error compensation and diagnosis It is entirely possible to tune and implement the near-field test for the ultra-low sidelobe antenna
