A dataset of radar-recorded heart sounds and vital signs including synchronised reference sensor signals

Radar systems allow for contactless measurements of vital signs such as heart sounds, the pulse signal, and respiration. This approach is able to tackle crucial disadvantages of state-of-the-art monitoring devices such as the need for permanent wiring and skin contact. Potential applications include the employment in a hospital environment but also in home care or passenger vehicles. This dataset consists of synchronised data which are acquired using a Six-Port-based radar system operating at 24 Ghz, a digital stethoscope, an ECG, and a respiration sensor. 11 test subjects were measured in different defined scenarios and at several measurement positions such as at the carotid, the back, and several frontal positions on the thorax. Overall, around 223 minutes of data were acquired at scenarios such as breath-holding, post-exercise measurements, and while speaking. The presented dataset contains reference-labeled ECG signals and can therefore easily be used to either test algorithms for monitoring the heart rate, but also to gain insights about characteristic effects of radar-based vital sign monitoring.雷达系统可实现心音、脉搏信号、呼吸等生命体征的非接触式测量。该方法能够解决现有主流监护设备的核心弊端，例如需永久布线以及与皮肤直接接触的问题。其潜在应用场景涵盖医院环境、家庭护理以及乘用车内。本数据集包含同步采集的多模态数据，采集设备包括工作于24吉赫兹（24 GHz）的六端口雷达系统（Six-Port-based radar system）、数字听诊器、心电图（ECG）以及呼吸传感器。本次实验共对11名测试对象开展测量，测试场景为多种预设工况，测量点位包括颈动脉、背部以及胸部的多个正面测点。整体而言，本次数据采集共获得约223分钟的有效数据，对应的测试场景包括屏气、运动后测量以及说话状态下的采集。本数据集包含带有参考标签的心电图信号，因此可直接用于测试心率监测算法，同时也可用于深入探究基于雷达的生命体征监测的特征效应。
