Radar microDoppler for security applications: Modeling men versus women

We created a model of human motion that was built upon extracted gait data, and calculated the spectrogram that would result from the radar measurements. We verified the model with several measurements. We modeled the radar Doppler signature of the component parts of the human body that build up the spectrogram, and verified the components. We then modeled the spectrograms of men versus women and compared these with some early measurements. The results show that this approach could be promising since small though measurable differences are apparent, though a larger study is necessary in order to adequately explore the issue.
