Intrusion location technology of Sagnac distributed fiber optical sensing system based on deep learning
IEEE Sensors Journal(2021)
摘要
For distributed fiber optical sensing based on Sagnac effect, the intrusion is usually located by notch frequency. However, the notch spectrum is the comprehensive result of the intrusion, so when multiple disturbances simultaneously intrude from different positions of the sensing fiber, it is impossible to establish a mathematical expression between the intrusion position and the notch frequency,...
