Ballistic target tracking and fusion is important to missile defense systems. A vital problem of in tracking and fusion is how to model the trajectory of ballistic missile target group accurately. This paper proposes a method to model the trajectory of ballistic missile, decoys and debris. The method uses pseudo-spectral method to determine the trajectory of a ballistic missile, is based on release model to establish the trajectory of decoys, and considers vanishing condition to model the trajectory of debris. The simulation results show the proposed method can obtain the trajectory of the ballistic missile target group and approximate the real situation with appropriate parameters.
