Abstract
In this article, wideband 3-D source localization utilizing only 1-D angle measurements based on a general distributed linear array (in lieu of planar array) network is studied. Instead of fusing the independent directions of arrival estimated by individual subarrays to form the final source location, a group sparsity-based localization method is proposed to exploit the information acquired by all receivers jointly with the corresponding closed-form Cramér-Rao bound for 3-D localization derived. Simulation results demonstrate that improved performance and robustness is achieved by our proposed method.
