| Abstract: | An algorithm of localization for multiple wideband sources by the use of data fusion of the multiple arrays is investigated in this paper.The covariance matri- ces of the multiple arrays are coherently fused into one of a reference array,and then locations of multiple sources are estimated.Multiple arrays are utilized to re- duce the resolution threshold and error,and improve the localization accuracy and robustness.Simulations are carried out to demonstrate the effectiveness of the pro- posed algorithm. |
