Aiming at the process and requirements of antenna parameters test, we analyze the main problems in the antenna parameters test, study the influence of environmental factors on measurements in the actual test process, and propose a design of an automatic test system based on virtual instrument technology for far field antenna performance parameters. We elaborate the system components and working principles, including the control principles of a vector network analyzer, an antenna test turntable and a derrick and the timing design of data acquisition. Combined with Matlab, we realize the error compensation of affecting factors and the testing calculation methods of antenna performance parameters, use da-tabase technology to accomplish antenna test data storage, read and report printing, and verify the reliability and feasibility of the scheme through field test experiment.
