摘要
利用雷达同时监测人体呼吸和心跳具有非接触、高隐私等优势,已成为当前国内外研究的热点之一。面向人体呼吸心跳同时监测场景,分析了不同类型的雷达系统工作原理,总结了在人体信号检测中的雷达数据预处理、呼吸和心跳信号分离以及呼吸率和心率估计的信号处理方法,指出了相关研究发展趋势。
Using radar to simultaneously monitor human respiration and heartbeat has the advantages of non-contact and high privacy,so it has become one of the research focuses at home and abroad.The working principles of different types of radar system are analyzed for the simultaneous monitoring of human respiration and heartbeat.The methods of radar data preprocessing,respiratory and heartbeat signal separation,and respiratory rate and heart rate estimation in human signal detection are summarized.Finally,the trends of detecting human vital signal based on the radar system are pointed out.
