Investigation on Method of Improving Precision for Radio Frequency Simulation System

摘要：

This paper presents an amendment method of system accuracy by calculating target with equivalent phase centre of antenna instead of mechanical position of antenna.At the very beginning,how RF simulation system works as a moving target has been briefly described.Then the error of RF simulation system consisted with spherical antenna array is also analyzed.Considering the total error comes from various errors of whole system,so we can substitute electrical position of antennas for that of target presented.Results of experiment show that most of the errors can be counteracted by using this method,and the simulation accuracy has been improved.
