Abstract:
1. A system for self-localizing acoustic sensors, said system comprising: an acoustic source positionable to generate an acoustic signal; a reference hydrophone positionable to have a source-to-reference distance along a first direction, and positionable to sample the acoustic signal to produce a reference sample set of collected data; a first acoustic sensor positionable to a first source-to-sensor distance along a second direction different from the first direction, and positionable to sample the acoustic signal to produce a first sensor sample set of collected data; and a processor positionable to determine a range difference error in response to a comparison of the reference sample set of collected data and the first sensor sample set of collected data, and positionable to correct at least partially an estimated range of the first source-to-sensor distance in response to the range difference error; wherein a first portion of the range difference error is used to correct the estimated range of the first source-to-sensor distance and a second portion of the range difference error is used to correct the source-to-reference distance.
