The AIA is designed to play both roles of radiating the radio-frequency signal and received the scattered-back signal, which is phase-modulated by the human chest movement. Moreover, a novel differentiator-based demodulator is proposed to acquire the vital signs from the modulated signal. The developed radar sensor has been successfully verified as the human subject is located at the distances of 1.5 m and 2.8 m away from the radar. Except for the compactness and low cost, the developed SIL AIA sensor has a frequency-scalable advantage to be realized in the millimeter-wave range for the sensitivity improvement.","PeriodicalId":177368,"journal":{"name":"2018 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115232161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the placement of the sensor nodes, an empirical channel model in combination with a cuboid body model was used, to estimate the individual transmission path losses by taking into account the influence of the human body.

Range-velocity spectrum obtained by a frequency modulated continuous wave (FMCW) radar identifies the range of multiple objects. Micro-displacement of each object is calculated based on the phase shift corresponding to each identified range by interferometry. Therefore, simultaneous micro-displacement measurement for multiple object recognition is achieved. Through evaluations using simulated and measured data, it is shown that the proposed MPI can simultaneously measure micro-displacement characteristics of multiple objects, i.e. a standing human and an idling car.
