Abstract: The near-space hypersonic glide vehicle (HGV) has the high maneuverability，which makes it difficult to track stably by using the single tracking model. To solve this problem，a tracking method based on adaptive multi-channel interacting multiple model is proposed. Based on the analysis of the force and maneuvering characteristics of HGV，the characteristics of strong adaptability of kinematic model and the high matching degree of dynamic model are fully considered in the proposed method. The kinematic model and the dynamic model are taken as a model set. The likelihood function value is used to adjust the transition probability matrix in real-time to enhance the proportion of the matching model. The residual edge distribution is used to describe the matching degree of the filtering model with the target motion in three different dimensions of x，y and z axes. Simulation experiments show that the proposed method has good adaptability in tracking HGV under typical control laws. When the HGV maneuvers，the proposed method has higher accuracy and stability.
