Abstract摘要非接触式人体生命体征微波探测仪设计摘要本项目探讨运用微波探测的方法，在一些特殊情况下无法通过直接接触人体进行人体生命体征探测时，进行非接触式人体生命体征的探测，例如无法接触式心率监控的严重烧伤病人，地震灾害时瓦砾下掩埋的生还者等的生命探测等。主要运用微波雷达，对人体的生命体征进行探测，从人体的心跳和呼吸两个方面，建立这两个人体生命的主要体征与微波雷达信号之间的科学联系；运用《信号与系统》与《数字信号处理》中的相关知识和方法，进行微波雷达信号的频谱变换，从信号的频率、幅度、脉冲特征等方面建立人体生命体征的微波雷达信号模型；进行人体衣物、瓦砾、墙壁等掩盖物的微波雷达衰减测试，进而为严重表皮烧伤的人体、瓦砾掩埋下的人体等无法接触人体的真实情况下的非接触探测，提供测试方法和数据的支持。关键词：非接触；生命体征；微波雷达；生命探测Non-contacthumanvitalsignsmicrowavedetectordesignABSTRACTThisprojectexplorestheuseofmicrowavedetectionmethod,Insomespecialcasessignsofhumanlifecannotbedetectedbydirectcontactwithhuman,non-contactdetectionofhumanvitalsigns,Suchassevereburnscannotcontactheartratemonitoringpatientsburiedunderrubblewhentheearthquakesurvivorsandotherlifedetectionandsoon.Themainuseofmicrowaveradar,thebody'svitalsignstodetect,Fromthehumanheartbeatandbreathingaretwoaspectstoestablishascientificlinkthetwomainsignsofhumanlifeandmicrowaveradarsignal;Theuseof"SignalsandSystems"and"DigitalSignalProcessing"intherelevantknowledgeandmethodsforspectraltransformmicrowaveradarsignals,Establishmentofhumanvitalsignsfromthefrequency,amplitude,pulsecharacteristicsandotheraspectsofmicrowaveradarsignalmodel;conducthumanclothing,rubble,wallsandotherobjectsconcealedmicrowaveradarattenuationtest,andthensevereskinburnsbody,buriedundertherubbleofthehumanbodyandothernon-contactprobecannotreachthetruthofthehumanbodyunderthesupporttestmethodsanddata.Keywords：Non-contact；VitalSigns；Microwaveradar；Lifedetection目录PAGE\*MERGEFORMATIII目录TOC\o"1-3"\h\uHYPERLINK\l_Toc846第1章绪论PAGEREF_Toc8461HYPERLINK\l_Toc175831.1课题来源及背景PAGEREF_Toc175831HYPERLINK\l_Toc210031.2国内外研究现状PAGEREF_Toc210031HYPERLINK\l_Toc276931.2.1国内研究进展PAGEREF_Toc276931HYPERLINK\l_Toc294621.2.2国外研究进展PAGEREF_Toc294622HYPERLINK\l_Toc191071.3选题意义PAGEREF_Toc191072HYPERLINK\l_Toc313781.4本文内容安排PAGEREF_Toc313782HYPERLINK\l_Toc52941.4.1人体生命体征的雷达信号表征研究PAGEREF_Toc52942HYPERLINK\l_Toc8080
