DISTRIBUTED SENSING SYSTEMS AND METHODS WITH SPATIAL LOCATION CORRELATION

摘要

Distributed sensing systems and methods with spatial location correlation of a reflection produced along an electromagnetic (EM) waveguide. A distributed sensing system comprises an EM waveguide, a distributed sensing interrogator, and a processor. The distributed sensing interrogator comprises a transmitter coupled to the EM waveguide and generates an interrogation pulse through the EM waveguide. The distributed sensing interrogator also comprises a receiver coupled to the EM waveguide and responsive to backscattered EM waves propagating through the EM waveguide. The processor determines a spatial location associated with a reflection produced along the EM waveguide using a return signal generated from the reflection by the interrogator and an interrogation signal including the interrogation pulse.
