Abstract: The disadvantage of traditional acceleration model based on dynamic pressure was analyzed according to dynamic characteristics of airbreathing hypersonic targets. Based on gravity turn modeling structure, a generalized model for tangent acceleration was proposed, along with an oblique shock model and a non-analytical model for normal. The mode space corresponding to these new models was analyzed with approximate calculation methods for hypersonic flow. A uniformly distributed model set was designed. The simulation results suggest the efficiency of the new model set for tracking hypersonic target with instant acceleration and turn.

Key words: hypersonic vehicle, maneuvering target tracking, dynamic model, multi-model approach
