MICRO-MOTION TARGET SENSING BY STEPPED-FREQUENCY CONTINUOUS-WAVE RADAR

Mechanical micro-vibration of a target may induce phase modulations on the radar echo, and the vibration can be detected to identify micro-motion target. In this paper, a new method to detect a micro-motion target and obtain its range and micro-motion frequency is proposed in which multiple periods...

description Mechanical micro-vibration of a target may induce phase modulations on the radar echo, and the vibration can be detected to identify micro-motion target. In this paper, a new method to detect a micro-motion target and obtain its range and micro-motion frequency 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. The experiment gives promising results.
