| Outline of Final Research Achievements |
In this study, we developed signal processing methods to improve the performance of radar-based human sensing. First, a blind signal separation algorithm using prior knowledge of physiological signals was developed to achieve high-resolution measurements, enabling the identification of human body parts. Next, we developed a high-dimensional clustering method that incorporates the features of respiration to enable simultaneous measurement of multiple people. In addition, a multi-radar sensing technique that integrates signals from multiple radar systems was also developed to solve the shadowing problem that occurs when numerous people are crowded together. The performance of these methods was quantitatively evaluated through radar measurements with the participation of subjects.
