Radar-based Measurement of the Body Movements of Multiple Students in Classroom Environments
Yu Oshima, Tianyi Wang, Masaya Kato +9
We demonstrate the feasibility of the radar-based measurement of body movements in scenarios involving multiple students using a pair of 79-GHz millimeter-wave radar systems with a…
Accurate Radar-Based Heartbeat Measurement Using Higher Harmonic Components
Itsuki Iwata, Kimitaka Sumi, Yuji Tanaka +1
This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, and the var…
Complex Number Assignment in the Topology Method for Heartbeat Interval Estimation Using Millimeter-Wave Radar
Yuji Tanaka, Kimitaka Sumi, Itsuki Iwata +1
The topology method is an algorithm for accurate estimation of instantaneous heartbeat intervals using millimeter-wave radar signals. In this model, feature points are extracted fr…
Radar-Based Noncontact Measurement of Heartbeat of Humans and Chimpanzees Using Millimeter-Wave Radar with Topology Method
Itsuki Iwata, Takuya Sakamoto, Takuya Matsumoto +1
This study proposes a method to determine the filter parameters required for the topology method, which is a radar-based noncontact method for measurement of heart inter-beat inter…
Radar-Based Respiratory Measurement of a Rhesus Monkey by Suppressing Nonperiodic Body Motion Components
Takuya Sakamoto, Daisuke Sanematsu, Itsuki Iwata +2
We propose a method to measure the respiration of a rhesus monkey using a millimeter-wave radar system with an antenna array. Unlike humans, small animals are generally restless an…
