Truly Distributed Coaxial Cable Sensing based on Random Inhomogeneities
Abstract
Inspired by Rayleigh backscattering based sensing methodology on an optical fiber, we present a novel sensing concept based on the random inhomogeneities on a coaxial cable. As an analogy of Rayleigh backscattering along an optical fiber length, "backscattering" also exists from a commercial cable due to its inherent defects along a cable length which induce a local variation. The accumulated back-scattered signals along the cable can be obtained using frequency domain reflectometry. By analyzing the shift in the local back-scattered signal, the local perturbations can be determined, so that truly distributed sensing capability using a coaxial cable can be achieved.
