摘要：

A fully coherent, continuous-wave (CW) radar operating near 10.5 GHz has been developed to record the radar signature corresponding to the walking human gait. The received signal is the sum of Doppler shifted signals reflected from the various parts of the moving body. Since the legs, arms, and torso all move at different relative velocities throughout the gait cycle, the human gait signature contains a wealth of information. Using signal processing techniques such as the short-time Fourier transform (STFT) and the chirplet transform, various parameters of the human gait can be extracted from the signal.
