Measurement Capability of the Interferometric Method of Sound Source Localization in the Absence of Data on the Waveguide Transfer Function

Resumo

The resolution of interferometric method of a sound source localization is analyzed. Two realizations of this method are presented, which do not call for the knowledge of the propagation medium characteristics for determining the source coordinates. These realizations solve the problem of identifying a low-noise source in water areas where acoustic calibration cannot be performed. The maximum applicability range of the method is estimated; this estimate makes it possible to optimize the source signal processing.
