Experiments for On-Line Bearing-Only Target Localization in Acoustic Array Sensor Networks~*

摘要

In this paper, we present a bearing-only on-line target localization platform, and succeed to realize the w hole 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.
