摘要：

A novel distributed fiber-optic sensor system based on phase generated carrier (PGC) for determining the position of disturbance is presented. The configuration and the operating principle of the system are illustrated, and the location mechanism is analyzed. The location of certain disturbance is obtained by means of the PGC demodulation technology with a new frequency domain location algorithm. Theory analysis and experiment results show that the proposed technology can realize the detection and location of the disturbing signals rapidly and effectively. This method is simply and can be obtained easily, it can eliminate the differences induced by the instability of detection signal, and can greatly improve the position accuracy.
