| 摘要: |
| 针对临近空间高超声速目标飞行速度快，跟踪预测难的特点，提出在中制导阶段进行最优弹道设计与弹道簇生成用于对目标预测命中区域进行有效覆盖的方法。通过分析临近空间高超声速目标对现有防空体系带来的挑战，阐明了在中制导段进行弹道簇设计与生成的必要性；将中制导段的弹道规划问题视为求解满足多种约束条件下的最优控制问题，应用最优化理论方法得到了基准的最优弹道；应用邻域最优控制理论，针对终端约束条件进行调整，设计了邻域最优弹道簇的生成算法。仿真验证了所提方法的有效性。 |

| Abstract: |
| Aimed at the high velocity and unpredictable trajectory characteristics of the hypersonic targets in near space, the optimal midcourse trajectory design and trajectory cluster generation methods were proposed for the effective coverage of the target’s predicted impact area. Firstly, by analyzing the challenges that the hypersonic targets have formed to the existing air defense systems, the necessity of the trajectory cluster design and generation in midcourse phase was illustrated. Secondly, the optimal midcourse trajectory design was treated as the problem of searching for optimal solutions under numerous constrains, and the nominal optimal trajectory was generated with the optimal control theory. Thirdly, based on the NOC (neighboring optimal control) theory, the neighboring optimal trajectory cluster generation algorithm was developed to meet the adjusted terminal constraints. Finally, the simulation results testify the effectiveness of the proposed method. |
