AI 中文摘要
本文介绍了Techtile测试床中用于分布式无线传感与定位的同步测量数据集Techtile（ARFT）的声学-射频融合内容。在Techtile测试床内部的二维空间网格的多个位置，同时发射并采集超声波与射频（RF）信号。每个采集周期对应一个漫游车停靠点、一个位置样本、一段声学记录和一个射频快照。射频模态以每主机导频测量值的形式记录，并以信道状态信息（CSI）张量的形式发布，这些张量对应安装在房间天花板上的42根天线。声学线性调频信号由91个同步麦克风记录，并由一个同步准全向扬声器发射。该测量活动覆盖了5011个空间位置样本，覆盖区域为5.57米×2.89米，且包含完整的射频与声学数据。本文详细说明了测量的记录方式、量化了每次实验的覆盖范围、描述了射频与声学数据的内容，并解释了对齐后的模态如何支持仅射频、仅声学及联合定位工作流程。此外，本文还阐述了一种静态声学定位流水线，该流水线执行锚点选择、脉冲压缩测距和最小二乘（LS）定位。
英文摘要
This paper documents the acoustic-radio fusion in Techtile (ARFT) dataset, a synchronized measurement campaign for distributed wireless sensing and positioning in the Techtile testbed. Ultrasonic and radio frequency (RF) signals are simultaneously transmitted and captured at multiple positions in a 2D spatial grid inside the Techtile testbed. Each acquisition cycle corresponds to one rover stop, one position sample, one acoustic recording and one RF snapshot. The RF modality is recorded as per-host pilot measurements and released as channel state information (CSI) tensors for 42 antennas mounted at the ceiling of the room. The acoustic chirp is recorded with 91 synchronized microphones and transmitted by a synchronized quasi omni-directional speaker. The campaign spans 5011 spatial position samples spanning a 5.57 m by 2.89 m area with complete RF and acoustic data. We detail how the measurements are recorded, quantify per-experiment coverage, describe the RF and acoustic data contents, and explain how the aligned modalities support RF-only, acoustic-only, and joint positioning workflows. Furthermore, a static acoustic positioning pipeline that performs anchor selection, pulse-compression ranging, and least squares (LS) localization is elaborated.
