Feature extraction and identification in distributed optical-fiber vibration sensing system for oil pipeline safety monitoring

Abstract High sensitivity of a distributed optical-fiber vibration sensing (DOVS) system based on the phase-sensitivity optical time domain reflectometry (Φ-OTDR) technology also brings in high nuisance alarm rates (NARs) in real applications. In this paper, feature extraction methods of wavelet dec...
