摘要
目的:为了满足雷达式非接触生命探测实验对探测目标同一性和稳定性的要求,设计研制一种用于模拟人体目标的人体呼吸运动模拟系统。方法:选取一种仿真人体的模型、一种双水平正压呼吸机以及合适的气囊和反射材料,根据人体呼吸运动的特点以及雷达式非接触生命探测实验对目标的要求,设计实现了一种能够自主定量模拟人体呼吸运动的系统。结果:该系统模拟出的呼吸运动波形与人体相似,且呼吸频率、幅度、吸呼时间比等参数可以调节,利用超宽带生物雷达进行测试,数据在统计学上具有同一性和稳定性。结论:该系统能够稳定地模拟人体的呼吸运动,并且满足多种环境条件下的探测需求,为非接触生命探测研究提供了稳定的探测目标和客观的评价标准。
Objective To develop a human respiration simulating system to meet the requirements of non-contact life detection experiment via radar in which target＇s movement has to be stable.Methods The CPR model,the double-level ventilator,the ballonet and the sheet metal for echo were selected.According to the characteristics of human respiration and the requirement of experimental target,a human respiration simulating system was developed.Results The frequency,amplitude and ratio of the inspiration and expiration of system were adjustable.The respiratory waveform of the system was similar with that of the human being.Tested by ultra-wideband radar,the data of system was statistically stable.Conclusion The system could stably simulate human respiration,meet the need of detection in various environments and provide an objective criterion for further study.
