Coherent combination method applied to distributed acoustic sensing over deployed multicore fiber
From Distributed Acoustic Sensing (DAS) measurements over deployed Multi-Core Fiber (MCF), we discuss several signal processing options to enhance the sensing sensitivity, namely core combination and longitudinal averaging.
