| 光学电磁场探测探针已逐渐开始在相控阵雷达天线测量等上应用，它的幅度和相位测量准确度受到大家重视。为了实现对光学电磁场探测探针测量能力准确标定，本文引入电磁场测量探头的标定思路，提出利用矩形金属波导的电场产生标准幅度及相位实现对光学电磁场探测探针标定的方法，建立了标定装置，阐述标定实施过程。通过实验验证，该方法能实现对光学电磁场探测探针标定，精度满足使用要求。 |
| 英文摘要: |
| Optical electric field probes have been gradually applied to measure the radiation capability of phased array radar antennas. Therefore, more attention is paid on how to accurately measure the amplitude and phase of this method. This paper introduces the idea of electric field probe calibration, and proposes a method of using electric field of the rectangular metal waveguide to generate a standard signal containing amplitude and phase to calibrate the optical electric field probe’s measurement capability. The design and production of the calibration device is elaborated in this paper. Experiment results show that this method is able to calibrate the optical electric field probe’s measurement capability, and the precision meets the requirements. |
