摘要： Methods, systems, and computer-readable storage media for accurate time delay estimation using coherent averaging. A plurality of out-of-bracket acoustical impulses are generated in a pipe segment of a fluid distribution system. Signal data representing the acoustical impulses sensed at two locations along the pipe segment are recorded. Precise timings for the generation of the acoustical impulses are obtained, and the acoustical impulses in the signal data recorded from the first location are averaged based on the precise timings to produce a near-sensor average impulse. Similarly, the acoustical impulses in the signal data recorded from the second location are averaged based on the same precise timings to produce a far-sensor average impulse. A time delay between arrival of the plurality of out-of-bracket acoustical impulses at the first and second locations is estimated from the timing of the near-sensor average impulse and the far-sensor average impulse.

摘要： Technologies are described herein for time-synchronizing sample data from independent recording devices utilizing samples tagged from a highly accurate time source. Datasets comprising samples representing a signal over a period of time are received from separate recording devices. A number of samples in each dataset are tagged indicating that the sample was taken immediately after a pulse in a PPS signal from a highly accurate time source onboard the recording device. The indices of the PPS-tagged samples, along with corresponding time values, are extracted from the datasets, and a set of common time values between the datasets is determined. A pair of frames of a specific length are extracted from each dataset aligned on the PPS-tagged samples corresponding to the common time values and comparative analysis is performed on the pair of frames.
