基于威胁特征点的启发式航迹规划方法

针对现有启发式航迹规划方法在决策变量、启发函数的选取和航迹表示方法等方面存在的不足，提出了一种基于威胁特征点的航迹规划新方法。该方法以导弹运动姿态角作为决策变量，通过引入特征点构造新的启发函数，以导弹经过空间的威胁度累积值、需用过载等为代价，结合导弹性能约束，采用龙格-库塔(Runge Kutta, R-K)积分得到平滑航迹。最后，以倾斜转弯面对称远程超音速导弹为例，通过攻防仿真实验，证明该方法规划生成的航迹满足各种约束条件且具有较高突防概率。

Heuristic route planning approach based on threat points

To avoid the shortcomings in the choice of decision variable, heuristic function and route expression, this paper proposes a new heuristic route planning approach that features some key threat points. The angle of attack, sideslip and roll are used as independent decision variables for decision-making. The cost function takes several factors into consideration, such as threat degree, overload and the distance to destination. Dynamic and kinematic constraint equations of the missile are established and a smooth trajectory is generated by Runge Kutta (R-K) integral. Finally, taking the bacd to turn (BTT) lateral symmetric long range supersonic missile as an example, simulation experiments are carried out to demonstrate the feasibility of the approach, which satisfies various constraints and can obtain an optimal route rapidly.
