Electromagnetic Modeling of Vital Sign Detection and Human Motion Sensing Validated by Noncontact Radar Measurements

Technology to analyze human motion has significantly advanced over the last few years. Locomotion studies have proved useful and have been practically applicable to some gait analysis. However, its use has been hampered by the amount of data generated and the limitations to the interpretation capabilities of this massive data. New techniques need to be developed to capture data rapidly, accurately, efficiently, and preferably remotely using noninvasive techniques. It is our goal to develop modeling capabilities and experimentally validate results to succeed in establishing models and practical ways to interpret this collected data. In this paper, electromagnetic models have been developed and validated using a software-defined radar to analyze different human motion sensing scenarios. Encouraging preliminary results have been achieved, and efforts will continue to analyze and model more motion scenarios.
