Abstract

Abstract : Usually source localization using sensor networks requires many sensors to localize a few number of sources, and it is still very troublesome to deal with coherent sources. When the three‐dimensional (3‐D) space are considered, the localization will become more difficult. A new approach is proposed to localize 3‐D wideband coherent sources based on distributed sensor network, which consists of two nodes and each node contains only two sensors. Direction‐of‐arrival (DOA) estimation is performed at each node by employing a new noise subspace proposed. Combining the pattern matching idea and the prior geometrical information of sources, a cost function is constructed to estimate the rough positions. A rotational projection algorithm is proposed to estimate the heights of sources and correct the rough positions, and consequently the localization of 3‐D sources could be achieved. Numerical examples are provided to demonstrate the effectiveness of this approach.
