| Outline of Final Research Achievements |
In this study, we investigated the human sensing technology based on MIMO system. The results of this study are mainly divided into two categories: (A) improvement of the accuracy of heart rate observation and (B) estimation of human position and status. As for (A), the conventional method of heart rate estimation using microwaves has a problem in its accuracy. In this study, we established a heart rate estimation technique with higher accuracy and stability than the conventional method by introducing a spatio-temporal signal processing technique. For (B), the analysis of the propagation channel characteristics obtained by the MIMO system has yielded a new method to estimate human status and behavior by extracting human positions and Doppler component distribution from the angular and time-varying characteristics in the reflected waves from the human body.
