Abstract :
In source localization, direction-of-arrival (DOA) estimate for the scattered source is more challenging than that for the point source. In this paper, we propose a new algorithm of estimating the parameters of multiple scattered sources based on UCAs with trimmed vector sensor. The proposed algorithm has significantly lower computational complexity and is robust to mis-modeling the spatial distribution of the scatterer.
