天线外场方向图自动测试系统

Automatic Test System of Antenna Out-field Directional Pattern

设计并实现了基于LabVIEW的天线外场自动测试系统,该系统改变了原有的手动天线测试方式,实现了测试天线与伺服系统的自动控制,能对天线转角、频率、功率等各项测试参数进行自动控制并绘制方向图,大大提高了天线测试的效率、精度,具有良好的扩展性。

This paper designs and implements the antenna out-field automatic test system based on LabVIEW. The system changes original manual antenna test mode, realizes the automatic control of test antenna and servo system,can automatically control each test parameter such as antenna rota- ting angle, frequency, power, etc. , and draw directional pattern, which can greatly improve the effi- ciency and accuracy of antenna test, and has good expansibility.
