Doppler spectrogram analysis of human gait via iterative adaptive approach

Doppler spectrogram analysis of the human gait is a useful tool for discriminating various micro Doppler tracks due to the movements of different body parts. A data-dependent algorithm, namely the short-time iterative adaptive approach, is used to obtain a more accurate spectrogram than the one provided by the conventional short-time Fourier transform-based approaches. The performance of the approaches is demonstrated and contrasted using both simulated and measured human gait data.
