| Abstract: | Human walking gait is one of the biological feature for recognition.The human echo signal to a CW radar contains the human gait feature.A human gait signal model is formed and based on the constructed test CW gait radar,the gait sampled signal is analyzed by time frequency method,and the methods for analyzing multi component non-stationary signal are discussed in detail.The comparison among the algorithm of STFT,WVD,Pseudo-smoothed WVD on gait sig-nal and its improvements is given,the basic method for gait ... |
