Spatial resolution analysis of dual-pulse ϕ-OTDR systems

Series

Abstract

This work analyzes the spatial resolution of the dual-pulse -OTDR systems by changing the dual-pulse parameters and demonstrates that the spatial resolution corresponds to half of the fiber region occupied by the dual-pulse train.
