Abstract

See full text

Apparatus is provided comprising a signal processor that receives signaling containing information about an acoustic signal swept and sensed over a frequency range in relation to a pipe; and determines information about the structure of the pipe based at least partly on two or more sub-frequency ranges that form part of the frequency range in the signaling received. The signal processor also receives the acoustic signal being transmitted to the pipe and corresponding signaling in the two or more sub-frequency ranges containing information about reflections of the acoustic signal back from the pipe; and determines information about the structure of the pipe based at least partly on a coherent mixing of the acoustic signal and the corresponding signaling in the two or more sub-frequency ranges using a coherent acoustic tomography technique. Alternatively, the signal processor also receives associated signaling in the two or more sub-frequency ranges containing information about associated resonance in a liner of a wall of the pipe and determines information about the liner of the wall of the pipe, based at least partly on the two or more sub-frequency ranges.
