Experiments for on-line bearing-only target localization in acoustic array sensor networks

In this paper, we present a bearing-only on-line target localization platform, and succeed to realize the whole process of target localization. In the experiment, five nodes are used to send their moving target bearing line data to a base station which adopts asynchronous pseudolinear (APL) estimator for localization. The performance of Direction-of-arrival (DOA) estimation is analyzed in both cases of static and moving target. The results show on-line single target localization is satisfying.
