Abstract

In this paper, an iterative algorithm for the location of multiple sources based on independent doublets arrays is proposed. The array brings a unified signal model for both near-field and far-field incoming sources. The signal model refrains the bias of Fresnel approximate due to the close displacement between elements of each doublet. Only exploiting the geometry of each doublet in direction-of-arrival (DOA) estimation, the proposed algorithm can avoid synchronization technology among different local oscillators of doublets, which means that elements among doublets could be independent. The proposed algorithm employs all the data received by the independent doublets arrays and can deal with more than two sources with only two coherent sensors in each doublet. The algorithm provides a simple approach and obtains acceptable results. Simulation results are illustrated to verify the effectiveness of the proposed algorithm.
