Abstract :
Remote sensing of human body is very useful in many services. The micro-Doppler characteristic of human body can be detected to identify life target. In this paper, another new theoretical method to obtain the range and Doppler frequency of human body is proposed in which multiple periods stepped- frequency continuous-wave signal and moving target indication (MTI) filter are adopted. The simulation results illustrate the validity of this method and present the detection of the target range and the vibration frequency of heart beating and breathing.
