The paper emphatically studies the way for solving the problem of track confusion in multiple targets tracking by using message fusion technique. The discussion is on the basis of measurement data of practical bistatic systems. At first the paper introduces the association algorithm used for multiple targets tracking in bistatic systems and points out that track confusion easily happens if dynamic state parameters are the only ones used for association process. Then it gives several association methods fusing data of target state, Doppler frequency (F/sub ds/) and radar cross-section (RCS). After analyzing characteristics of F/sub ds/ and RCS data, the paper suggests two fusion modes-cascade fusion and parallel fusion. Both modes can decide whether or not to use F/sub ds/ data according to its change. From one hundred statistical results it is clear that track confusion frequency drops greatly when using data fusion techniques.
