Abstract

In the paper, a non-contact vibration retrieval method was presented and the performance was analyzed based on linear frequency modulation continuous wave (LFMCW) radar. Firstly, the backscattered signal model of a vibrational target was introduced with the stop-go assumption. Then a vibration retrieval method was proposed by extracting phase based on the backscattered signal model of a vibrational target. The influence of noise and clutter on vibration retrieval was analyzed, and the signal noise ratio of vibration measurement was obtained. Finally, the validity of the performance analysis was verified by computer simulations. In addition, the experimental data acquired by LFMCW radar was used to test the proposed method.
