【摘要】 为了使天线测试系统能有较高的测试精度,系统需具备水平圆周方向、俯仰方向和水平直线方向均可转动且转动精度非常高的天线转台;还需具备宽频率范围、高灵敏度的信号发射与接收处理装置;同时需具备操作方便、可精确控制天线转台和矢量网分仪以及能把测量的数据显示并保存、处理的测试软件。利用高精度天线转台和矢量网络分析仪,开发设计相应的自动测试软件,并进行天线相位中心的标定,为高精度天线相位中心的应用奠定了基础。更多还原

【Abstract】 The antenna test system should contain an antenna turntable that could move very precisely in azimuthal direction,in tilted direction,in horizontal linear direction.This system should also have signal transmitter and receiver with wide frequency range and sensitivity.Finally,the system should also contain the test software that could be operated easily and control the turntable and vector network analyzer precisely and display,save,process the tested data.Based on the high precision antenna turntable and vector network analyzer,the corresponding automatic test software is developed and used.Besides,the antenna phase center is calibrated,and this would lay a foundation for the application of antenna phase center.更多还原
