Aiming at the measurement process and parameters requirements of antenna test, the main problems in the antenna parameters test are analyzed, and the actual test environment in the process of the influence of factors on the antenna parameters measurement results are studied. A design of far field antenna performance based on LabVIEW parameters auto- matic test system is proposed. The system component and working principle of the scheme are elaborated in detail, including the vector network analyzer, the antenna test turntable and control principle of the derrick and timing design of data acquisi- tion. Combined with Matlab, the error compensation of affecting factors and the testing calculation methods of performance parameters of the antenna are realized. Database technology is used to accomplish antenna test data storage, read and report printing. Field test experiment verifies the reliability and feasibility of the scheme.
