In this study, a low-cost continuous wave (CW) radar system with 3D-printed high-gain horn antennas called VitRad is proposed for human vital sign detection. The CW radar consists of 3D-printed high-gain horn antennas, commercially available low-cost surface-mounting devices, and monolithic ICs. The CW radar system operates at a frequency band of 5.8 GHz, and the backscattered I/Q data are collected using a digital storage oscilloscope (DSO). The data is processed on MATLAB to determine vital sign information such as respiratory and heartbeat rates. It is demonstrated that the proposed CW radar system for vital-sign monitoring can effectively measure respiratory and heartbeat rates.
在本研究中,提出了一种名为VitRad的低成本连续波(CW)雷达系统,该系统配备3D打印的高增益喇叭天线,用于人体生命体征检测。该连续波雷达由3D打印的高增益喇叭天线、市售低成本表面贴装器件和单片集成电路组成。该连续波雷达系统工作在5.8 GHz频段,使用数字存储示波器(DSO)收集反向散射的I/Q数据。数据在MATLAB上进行处理,以确定诸如呼吸和心率等生命体征信息。结果表明,所提出的用于生命体征监测的连续波雷达系统能够有效地测量呼吸和心率。
