| Zusammenfassung | To perform near field antenna measurements with uncrewed aerial vehicles (UAVs), the UAV mounted antenna is connected to the ground-based vector network analyzer via a radio frequency over fiber (RFoF) link, since coaxial cables tend to be too bulky. Utilizing bi-directional signal transmission, the actual measurement- and a feedback signal are transmitted through the same optical fiber so that the variability of both the attenuation and phase shift in the signal path due to environmental effects can be continuously compensated. Further, an extended approach to the VNA system error correction must be used to determine the static error parameters of the whole system, since standard methods cannot be applied due to the entire RFoF link being limited to uni-directional transmission. This article shows the compensation method, an extended system error correction method with a validation of both and an estimation of the remaining uncertainty. |
