论文根据吸气式高超声速目标的力学特性，对传统动压加速度模型的局限性做了分析。基于重力转弯模型框架，提出了切向加速度的推广模型和法向加速度的斜激波、非解析混合模型。随后基于高超声速流场工程近似算法对吸气式高超声速目标的模式特征进行分析，并设计了均匀模型集。仿真研究表明，新的模型集能够较好地适应目标突然加速和转弯机动，有效跟踪助推跳跃机动的吸气式高超声速目标。
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.
