Localization of low-frequency coherent sound sources with compressive beamforming-based passive synthetic aperture.
The localization of low-frequency coherent sources requires a proper aperture to ensure a high spatial resolution. Attaining a large aperture is difficult in practice when the conditions involved are limited. This letter investigated a compressive beamforming-based passive synthetic aperture approach with a reference sensor in a fixed position. Localization findings on acoustic sources in a semi-anechoic chamber were compared with conventional beamforming, compressive beamforming, passive synthetic aperture, and compressive beamforming-based passive synthetic aperture. Results suggest that the proposed method can produce a higher spatial resolution and higher detection ability than the others.
