Research summary
Development and Applications of Millimeter-Wave-Based Sensing, Radar Signal Processing, and Motion Information Analysis: Our laboratory develops fundamental technologies and applications for wave-based sensing, radar signal processing, and motion information analysis, with a particular focus on microwave and millimeter-wave radar. A central technical concept in our research is the combination of high-resolution radar imaging and the intensive use of motion information. In many radar research fields, high-resolution range and angle estimation are regarded as key technologies, especially for millimeter-wave radar. In our laboratory, we additionally emphasize the use of motion-related information such as velocity, acceleration, Doppler velocity, and micro-Doppler signatures. By exploiting such motion information, we aim to overcome limitations that cannot be solved by position estimation alone. Radar sensing is often valued because it can work under conditions where cameras and LiDAR are limited, such as low-light environments, smoke, dust, fog, and privacy-sensitive spaces. In addition to these advantages, our laboratory focuses on the technical strength of radar: the remote and high-resolution measurement of velocity and motion. We develop signal processing methods and practical sensing techniques based on this perspective. Using these radar-based motion sensing technologies, we work on applications in vehicle and robot sensing, healthcare monitoring, human motion analysis, and clothing comfortability evaluation.
