| 摘要: |
| 针对高超声速滑翔导弹跟踪中状态模型构建问题，研究基于制导变量变化规律的气动参数建模方法。对气动参数进行分析，指出传统建模方法的缺点。在假设制导变量服从一阶时滞过程的前提下，利用线性化的气动系数推导气动参数模型，通过分析不同飞行状态下的模型变式，证明模型对目标机动具有自适应性。对模型中未知参数的取值问题进行讨论，实现模型与飞行状态的自适应匹配。仿真结果表明：当目标发生机动时，所提模型性能明显优于传统模型。同时，在不同滤波器参数条件下的仿真结果进一步证实了模型的有效性。 |

| Abstract: |
| Aiming at the modeling problem of hypersonic gliding missile tracking, a method of aerodynamic parameter model based on the law of guidance variables was studied. The aerodynamic parameters were analyzed and the shortcomings of the traditional modeling method were pointed out. With the assumption that the guidance variables obey the first-order delay process, the aerodynamic parameter model was derived by using the linearized aerodynamic coefficients. By analyzing the variants of model under different flight conditions, the model adaptability for target′s maneuver was proved. The values of unknown parameters were discussed, so as to realize the adaptive matching of model with flight state. Simulation results show that the performance of the proposed model is obviously better than the traditional model when the target is maneuvering. Simultaneously, the simulation under different filter parameters confirms the model′s validity. |
