Abstract
A distributed acoustic sensing (DAS) system may include an optical fiber, a phase-sensitive OTDR (φ-OTDR) coupled to the optical fiber, and a processor cooperating with the φ-OTDR. The processor may be configured to generate a series of covariance matrices for DAS data from the φ-OTDR, and determine an acoustic event based upon comparing the series of covariance matrices with a corresponding Toeplitz matrix.
