Abstract: This paper proposes a vibration location method based on spatial-frequency analysis, which can help achieve better location performance in the application of φ-OTDR. The method is proven to be able to separately locate coupled vibration events to some extent, achieve break-the-pulse-width-limit spatial resolution in the case of single event detection with higher robustness, and provide more comprehensive information about the vibration situation to better identify vibration events, noise and disturbance. Different experiments including indoor and outdoor tests are conducted to practically validate the effectiveness of the method and its advantages over the conventional moving differential method. Experiment results show that the proposed method exhibits several useful merits.
