Signs of life detection behind obstacles using an UWB radar sensor

The "Signs of life detection behind obstacles using an UWB radar sensor" dataset was created by University of West Attica, by collecting data from 9 people using an UWB sensor, which was the X4M200 UWB radar sensor by Novelda, with and without the existence of a wall between the subject and the radar for the purposes of RESCUER project (https://rescuerproject.eu/ - a Horizon 2020 Research & Innovation Programme under Grant Agreement No.101021836). In all cases, the subject was lying down in the same stance for about 1 min and the radar was placed in four different positions: a) 0.2 m from the ground, b) 0.5 m from the ground, c) 1 m from the ground, d) 1 m from the ground and with a 45 degree angle. For comparison purposes, we also include in the dataset the case where no human is present within the radar's detection area. The subjects were placed in a distance between 0.5 and 5 metres from the radar and different stances were considered, while data were collected both for the amplitude (designated as abs) and the phase of the signal (designated as angle). This information is designated in each filename. For example, the filename "2 facing radar abs.csv", indicates that the subject is placed in 2 metres away from the radar, he/she is facing the radar and the file contains the signal's amplitude. The sampling rate of the radar was set to 17 samples per second and a distance step of about 0.05144 m was also considered.

“基于超宽带（UWB）雷达传感器的障碍物后方生命体征检测数据集”由西阿提卡大学（University of West Attica）为RESCUER项目（https://rescuerproject.eu/，隶属于欧盟地平线2020研究与创新计划，资助协议编号为No.101021836）构建。本数据集通过9名受试者的采集数据得到，所用传感器为Novelda公司的X4M200超宽带雷达传感器。采集场景包含两类：受试者与雷达之间存在墙体遮挡，以及无墙体遮挡。所有采集场景中，受试者均以固定躺卧姿态持续约1分钟，雷达设置于四种不同安装位置：a）距地面0.2米；b）距地面0.5米；c）距地面1米；d）距地面1米且呈45度倾角。为便于对比分析，数据集同时纳入了雷达探测范围内无人类受试者的空白对照场景。受试者与雷达的间距介于0.5米至5米之间，且涵盖多种不同姿态。采集数据涵盖信号幅度（标记为abs）与相位（标记为angle）两类参数，两类参数的标识均包含在文件名中。例如，文件名"2 facing radar abs.csv"表示：受试者与雷达间距为2米、正对雷达方向，该文件存储的内容为信号幅度数据。该雷达的采样率设置为每秒17个采样点，同时采用约0.05144米的距离步长完成数据采集。
