A Real-time Compensation Method for High Precision Antenna Test Turntable

doi:10.12060/j.issn.1000-7202.2022.01.08

Abstract

Abstract: Antenna turntable is an important part of radome electrical performance test system,which requires high precision.Due to the characteristics and installation of the magnetic gate,the magnetic gate sensor’s accuracy sometimes can not meet the system requirements,which needs compensation.In this paper,the causes of magnetic gate precision errors are analyzed in detail,and the software real-time compensation method is put forward and the compensation principle is expounded.Finally,this real-time compensation system is verified to have better compensation effect and meet the requirements of indicators through experiments.

Key words: Turntable, Magnetic gate sensor, Accuracy compensation, Error analysis, Close-loop control
