abstract

Signal processing is studied for Sagnac fiber distributed sensors. Wavelet de-noising and wavelet decomposition are comparatively used to analyze signals in frequency domain to give smoothed frequency spectra, based on which null frequencies of the spectra are found more accurately. The analysis is helpful to more accurately locate the disturbance.
