数字天线阵列的多天线单元和多收发通道间存在幅度相位误差,所以必须对其进行校正和测试以消除这些误差对系统性能影响。介绍利用虚拟仪器系统开发平台——LabVIEW和PCI-6534数据采集卡,完成阵列天线测试过程中校正和波瓣测试的数据采集。
Amplitude phase errors exist between multiple antenna elements and multiple transceivers of a digital antenna array, so they must be calibrated and tested to eliminate the effect these errors have on system performance. Introduce the use of virtual instrument system development platform - LabVIEW and PCI-6534 data acquisition card to complete the array antenna testing process of calibration and lobe data acquisition.
