Modeling and simulation study on radar Doppler signatures of pedestrian

This paper focuses on radar Doppler signatures of pedestrian. Firstly, an improved human walking model which describes a pedestrian as a linear-rigid target is introduced. Then radar echoes of the pedestrian under the condition of continuous wave (CW) radar signal are acquired, formulas of instantaneous Doppler are derived and movement signatures of the target are analyzed. Simulation experiments are carried out to validate the model and theoretic analysis.
