Phase Noise Suppression in Phase-Sensitive OTDR Using Fault-Tolerant D-S Evidence Theory

The phase noise caused by various factors will lead to the distortion of phase demodulation in phase-sensitive optical time domain reflectometer. In order to suppress the phase noise, a data fusion technology based on fault-tolerant D-S evidence theory is introduced for phase demodulation. The multi...
