| Abstract(in English) | Radar-based noncontact heart rate measurement technology has been attracting increasing attention. However, the authors have found that the accuracy in heart rate significantly deteriorates depending on the position and posture of the subject. In this report, scattering waves are numerically generated by applying the physical optics approximation to a numerical human body model obtained from a depth camera image. We assume a use of a millimeter-wave multiple-input multiple-output array radar and investigate the performance of an adaptive array technique for forming an optimal beam directed at the position of the dominant reflection position on the human body. Using the proposed method, it has been clarified that the array antenna pattern is automatically directed to the reflection position that changes over time. The simulation results indicate the remarkable tracking performance that allows for accurate noncontact heartbeat measurement that is robust against complicated motion of a human body. |
