摘要
毫米波雷达能够非接触性地检测电磁波信号,FMCW毫米波雷达传感器能采集生命的呼吸和心跳等特征信号。对FMCW毫米波雷达的原理和人体生命体征信号研究分析,提出了多路信号复用技术探测方法。采用FMCW毫米波雷达传感器,STM32芯片为主控制器的方法,结合Wi-Fi无线通信技术设计一个生命探测系统。经过实验测试,系统可以在短距离非接触条件下探测生命体征信息。
Millimeter wave radar can detect electromagnetic wave non-connectively,and FMCW millimeter wave radar sensor can collect characteristic signals of life such as breathing and heartbeat.The principle of FMCW millimeter wave radar and human vital sign signal are studied and analyzed.A life detection system is designed by using FMCW millimeter wave radar sensor,STM32 chip as the main controller and Wi-Fi wireless communication technology.After experimental tests,the system can detect vital signs in short distance non-contact conditions.
