摘要随着人类对自身健康的不断关注，现代人类已经不再仅仅满足于发现病症后再接受治疗，他们更倾向于将疾病扼杀在摇篮里。这就势必要求出现新型的医疗器械，能够对人体的生命体征（呼吸与心跳）实施健康监测。雷达技术的不断完善使这一设想变为可能。现代医学监测人体生命体征时，接触型医疗器械一方面局限了人体的自由活动给被监测者带来不便，另一方面易影响造成被监测者的情绪变动引起生理变化给监测结果造成一定误差。由此，基于雷达的无接触测量方法势必需要得到推广。本文拟将多普勒雷达应用到人体生命特征(呼吸与心跳)的检测上来，将传统意义上多用于国防领域的雷达技术和生物医学工程领域相结合，这种创新型的结合方式的应用前景十分广阔。文章对多普勒雷达及其在非接触式测量方面的应用进行了深入的研究，主要研究工作如下：（1）利用软件ADS对多普勒雷达系统进行理论建模，完成理想情况下的系统仿真，并逐渐推广到使用实际器件参数的系统仿真；（2）在系统仿真的基础之上，试制基于多普勒雷达的人体生命体征非接触式检测样机，并设计验证实验的方案，利用样机开展无接触人体生命体征检测实验，验证该设想与实验装置的可行性；（3）开拓多普勒雷达非接触式测量的应用前景，将其推广到建筑领域，用于测量极端天气下的高层建筑物振动频率以及大型桥梁结构振动频率，设计其测量装置及测量方法。80587

Title    Radar Non-contact Monitoring of Vital Signs     

Abstract With the increasing attention to human health, people are not satisfied with curing disease after seeing a doctor any more。 They need new medical apparatus and instruments that can monitor vital signs 。 The improving development of radar makes it possible。 On the one hand, contact-type health monitoring is inconvenient to measured object by confining nor inhibiting them。 On the other hand, contact-type health monitoring is easy to bring error because of changes of mood of measured objects。 Therefore, non-contact measurement method must be popular in the future。 This paper aims to apply Doppler radar to monitoring of vital signs combining radar technology traditionarily used in national defense with biomedical engineering, which promises a broad developing in the future。 The paper focuses on the study of Doppler radar, the main work is as follow: 1)Doppler radar modeling system is established and simulated with ADS in ideal circumstances and the simulation approaches real environment inch by inch; 2)After radar system simulation, non-contact monitor prototype of vital signs is made on the basic of Doppler radar。 What’s more, verification test is designed to validate the prototype reliability; 3)The application prospect of non-contact measurement method of Doppler radar is developed in architectural industry to measure building jitter frequency in extreme weather conditions, and the equipment and the measurement method are designed。
