Abstract

A detection system based on the laser micro-Doppler effect for detecting vibration-properties of moving target was developed. This system can detect the micro-Doppler effect induced by vibration whose order of magnitude is micrometer well. Frequency domain analysis and time-frequency joint analysis of experimental results showed that the complex vibration of target can be effectively detected by laser micro-Doppler effect, and also the application range of laser micro-Doppler effect is further extended. The results of feature extraction indicate that time-frequency analysis method is fit for the analysis of time-varying micro-Doppler signal, and the vibration signature of the moving target can be effectively extracted. The experimental results are shown that it confirms the efficiency of this system.
