Abstract

In order to enhance the signal-to-noise-ratio of a distributed acoustic sensing system based on Φ-OTDR, we proposed the combination of segmented unwrapping algorithm, averaging estimation of phase difference and IIR filtering method. The enhancement of signal quality is numerically demonstrated.
