Sparsity-based localization of spatially coherent distributed sources

Wenmeng Xiong, José Picheral, Gilles Chardon, Sylvie Marcos

ICASSP 2016accepted

In this paper, the localization of spatially distributed sources is considered. Based on the problem formulation of the Deconvolution Approach for the Mapping of Acoustic Sources (DAMAS), a criterion based on a convex optimization under sparsity constraint is proposed to locate the sources. Also an…

Performance analysis of music in the presence of modeling errors due to the spatial distributions of sources

Wenmeng Xiong, José Picheral, Sylvie Marcos

ICASSP 2015accepted

In this paper, the direction of arrival (DOA) localization of spatially distributed sources impinging on a sensor array is considered. The performance of the well known MUSIC estimator is studied in the presence of model errors due to angular dispersion of sources. Taking into account the coherently…
