Autofocus Method for Human-Body Imaging under Respiratory Motion Using Synthetic Aperture Radar
Masaya Kato, Takuya Sakamoto
This study presents an effective autofocusing approach for synthetic aperture radar imaging of the human body under conditions of respiratory motion. The proposed method suppresses…
Radar-Based Identification of Individuals Using Heartbeat Features Extracted from Signal Amplitude and Phase
Haruto Kobayashi, Takuya Sakamoto
This study proposes a non-contact method for identifying individuals through the use of heartbeat features measured with millimeter-wave radar. Although complex-valued radar signal…
Deformation-Aware Observation Modeling for Radar-Based Human Sensing via 3D Scan-Depth Sequence Fusion
Guangqi Shi, Kimitaka Sumi, Takuya Sakamoto
Non-contact radar-based human sensing is often interpreted using simplified motion assumptions. However, respiration induces non-rigid surface deformation of the human body that im…
Millimeter-Wave Radar Sensing of Wombat Respiration
Marina Murakami, Ryoko Iwase, Chiemi Iba +2
This study demonstrates the feasibility of radar-based non-contact respiratory monitoring for wombats. Two measurement experiments were conducted in June and December 2024 using 79…
Simulation for Noncontact Radar-Based Physiological Sensing Using Depth-Camera-Derived Human 3D Model with Electromagnetic Scattering Analysis
Kimitaka Sumi, Takuya Sakamoto
This study proposes a method for simulating signals received by frequency-modulated continuous-wave radar during respiratory monitoring, using human body geometry and displacement…
