摘要

Since Phase-sensitive Optical Time Domain Reflectometer (Φ-OTDR) fiber optic warning system is extremely sensitive to the environment, how to improve the signal noise ratio and make useful signal apparent among the noise has become the key area of research. The working principle of Φ-OTDR distributed fiber optic system is analyzed. Three commonly used algorithms are introduced with separating averaging and difference method, moving averaging and difference method and wavelet threshold de-noising method. A localization algorithm is proposed based on wavelet high frequency component by analyzing digging signal's variation with distance. This localization algorithm can highly improve the sensitivity of the system and realize the noise ratio as 9.6033dB.
