本文提出并描述了一种利用配备UHF-RFID阅读器的无人机进行无源标签定位的测量方法。该方法基于合成孔径雷达方法，并利用阅读器/无人机轨迹的知识，这是通过差分全球导航卫星系统实现的。通过数值模拟和实验结果分析了不同测量不确定度来源。讨论了方法能力与阅读器轨迹的长度和形状的关系。最后，通过商用RFID硬件和微型无人机的实验分析，验证了该定位方法的有效性。
This paper presents and characterizes a measurement method for positioning of passive tags, by a drone equipped with a UHF-RFID reader. The method is based on a synthetic aperture radar approach and exploits the knowledge of the reader/drone trajectory, which is achieved with a differential Global Navigation Satellite System. Different sources of measurement uncertainty are analyzed by means of numerical simulations and experimental results. The method capabilities are discussed versus the length and shape of the reader trajectory. Finally, the proposed localization method is validated through an experimental analysis carried out with commercial RFID hardware and a microclass unmanned aerial vehicle.
