Summary

This summary is machine-generated.

This study explores beyond-line-of-sight sound source localization using acoustic diffraction. Experiments show that a minimum variance distortionless (MVD) processor can localize sources with shadowed microphone arrays, especially when the array aperture is parallel to the diffracting edge.

Area of Science:

Acoustics
Signal Processing
Array Signal Processing

Background:

Acoustic diffraction enables sound propagation around obstacles, offering potential for beyond-line-of-sight (BLOS) sensing.
Traditional localization methods often require direct line-of-sight, limiting their application in complex environments.

Purpose of the Study:

To investigate the feasibility of localizing sound sources using acoustic diffraction with fully shadowed microphone arrays.
To assess the performance of matched-field (MF) processors under shadowed conditions.

Main Methods:

Simulated and experimental investigation of sound source localization in a shadowed region.
Utilizing a 90° wedge as an obstacle and a 16-element line microphone array.
Employing matched-field (MF) ambiguity surfaces and Bartlett and minimum variance distortionless (MVD) processors.

Main Results:

The minimum variance distortionless (MVD) processor demonstrated capability for source localization with fully shadowed arrays.
Optimal performance was observed when the array aperture was significantly parallel to the wedge's edge.
Localization performance degraded significantly below a signal-to-noise ratio of 40 dB.

Conclusions:

Sound source localization is achievable even when the receiving array is in the acoustic shadow of an obstacle.
Array configuration, particularly its orientation relative to the diffracting edge, is critical for successful shadowed localization.
The MVD processor shows promise for BLOS acoustic sensing applications in complex environments.
