In order to improve the phased array tracking performance, a target tracking method based on data fusion is presented for measurement information of multisource. In the method, data extrapolation and time delay correction, data detection, coordinate transform are carried out in turn. Then smooth filtering for measurement data is carried out and data fusion through dynamic weighted, which improves tracking and predicting performance, is used at last. The simulation result shows that the proposed target tracking method based on dynamic weighting data fusion has higher accuracy of tracking, which can meet requirement of system.
