标题： DragonFly: Single mmWave Radar 3D Localization of Highly Dynamic Tags in GPS-Denied Environments

摘要： 动态目标的精确定位和跟踪，例如在GPS不可用的室内环境中设备、人员、车辆、无人机、机器人及其交互的资产，对于实现下一代空间感知工业设施的安全高效操作至关重要。本文介绍了DragonFly，这是一种使用单输入多输出毫米波雷达的高动态散射标签三维定位系统。该系统通过引入关键的多普勒去模糊算法和一个完全集成的交叉极化介质透镜式毫米波ID标签，首次展示了能够利用多输入多输出雷达能力的毫米波散射系统，该标签在高速和高加速度下以及远距离情况下进行三维定位，功耗仅为68微瓦。DragonFly在静态和动态配置中进行了广泛评估，包括在飞行的四旋翼无人机上，并与多个基线进行了比较，证明了其能够在速度和加速度约为10米/秒-1和4米/秒-2的情况下，以及在高达50米的距离下，以中位数3D精度12厘米跟踪多个标签的能力。 显示英文摘要

摘要： The accurate localization and tracking of dynamic targets, such as equipment, people, vehicles, drones, robots, and the assets that they interact with in GPS-denied indoor environments is critical to enabling safe and efficient operations in the next generation of spatially aware industrial facilities. This paper presents DragonFly , a 3D localization system of highly dynamic backscatter tags using a single MIMO mmWave radar. The system delivers the first demonstration of a mmWave backscatter system capable of exploiting the capabilities of MIMO radars for the 3D localization of mmID tags moving at high speeds and accelerations at long ranges by introducing a critical Doppler disambiguation algorithm and a fully integrated cross-polarized dielectric lens-based mmID tag consuming a mere 68 uW. DragonFly was extensively evaluated in static and dynamic configurations, including on a flying quadcopter, and benchmarked against multiple baselines, demonstrating its ability to track the positions of multiple tags with a median 3D accuracy of 12 cm at speeds and acceleration on the order of 10 m/s-1 and 4 m/s-2 and at ranges of up to 50 m.
