Improved location algorithm for multiple intrusions in distributed Sagnac fiber sensing system

An improved algorithm named “twice-FFT” for multi-point intrusion location in distributed Sagnac sensing system is proposed and demonstrated. To find the null-frequencies more accurately and efficiently, a second FFT is applied to the frequency spectrum of the phase signal caused by intrusion. After...
