Abstract :
The Doppler spectrogram of a moving human is characterised by microDoppler returns due to the dynamic movements of the different body parts. The reassigned joint time-frequency transform is applied to study these distinct microDoppler features. Reassigned spectrograms generated from a simulation model and measured data are presented and analysed.
