摘要

In this paper, ultra-wideband (UWB) Doppler radar signatures from walking human subjects are processed with the state-space method (SSM) to analyze compressed radar echoes for the first time. A new mathematical model is proposed to detect the human walking strides using UWB radar, while microDoppler (μ-D) features are extracted for gait analysis using shorttime SSM (STSSM). To distinguish μ-D sign...
