Features Extraction of the Doppler Frequency Signature of a Human Walking at 1 GHz
A preliminary Doppler analysis on a man walking in free space at 1 GHz is presented in this paper. Firstly, the back-scattered response of the moving target has been provided by a simulation tool based on physical optics (PO) theory. Then, a short-time Fourier transform (STFT), a reassignment spectrogram (RE-Spect) and a Wigner-Ville distribution (WVD) have been employed to the data, in order to characterize the micro-Doppler signature of the walking human body. The results are based entirely on numerical tests. The investigation on the time variations of the Doppler spectrum of moving targets at lower frequencies is of interest for the emerging radar applications devoted to the detection and tracking of people in highly cluttered environment.
