Research summary
Wave Information Processing for Radar/Sonar-based Motion Sensing Our research focuses on motion sensing and analysis technology based on radar and sonar systems. In addition to conducting basic research on the fundamental technology of radio and ultrasound wave information processing, we are also engaged in a wide range of applied research that extends into the fields of biomechanics and epidemiology. In our basic research, our aim is to clarify the fundamental characteristics of moving object tracking systems, develop design methodologies, and create imaging technology for kinematic information such as position, velocity, and acceleration We are also interested in measuring human motion, with a focus on applications in healthcare, surveillance, and intelligent transportation systems. For healthcare systems, we are investigating novel microwave radar systems that can detect cognitive impairments via measurements of daily walking and sit-to-stand movements without compromising privacy. Furthermore, we are developing monitoring systems that use wave measurement to detect human bodies in blind areas, including behind walls and cars, which can be challenging to measure using other sensors like cameras and lidars.
