Abstract
An object moving along a conduit having multiple channels is tracked. Each channel defines a portion of a length of the conduit. For each channel, acoustic data, generated from one or more acoustic signals detected at the channel in response to movement of the object along the conduit, is generated. For at least one channel, the acoustic data obtained for the at least one channel is cross-correlated with the acoustic data obtained for at least one other one of the channels. Based on the cross-correlating, a position of the object within the conduit is determined.
