ABSTRACT

This chapter examines the human gait with and without the use of a cane as an assistive walking device. It analyzes various attributes of the motions of the feet, and the upper and lower parts of the leg, and shows how to separate these motions from that of the cane. In particular, the chapter points out the saddle differences in the gait time–frequency signal representations when the person is walking toward and away from the radar. It uses both the spectrograms and the cadence velocity diagram (CVD) for extracting the features that reveal these differences. The chapter introduces the fundamentals of human gait analysis. It presents the radar signal model for human monitoring. Further, it provides the analysis of human gait motion signature in the cadence-velocity domain along with the general framework for micro-Doppler gait signature classification. Using experimental data, the chapter reveals the distinct human gait patterns for different walking styles in both time–frequency and cadence-velocity signal representation.
