Abstract
The human gait is a complex mechanism by which a variety of muscles and bones must work together in precise coordination to create characteristic human locomotion, which can be used as an identification or clinical gait characterization for detecting pathological conditions. In this paper, a contact-free detection system for human gait based on continuous-wave bio-radar is introduced. Through the spectrum analysis of the radar echo signal generated during human walking, the main frequency of the human gait signal is extracted. Correlation analyses are made with the data obtained from the acceleration sensor. The experimental results show that the bio-radar can detect the gait signal of human walking, and it is consistent with the result of acceleration and video monitoring.
