巡航导弹中制导阶段航迹规划算法

巡航导弹作为一种精确打击武器在现代战争中发挥着越来越大的作用。文中总结了飞行器航迹规划算法和地面防空威胁的建模方法，并结合巡航导弹自身特点提出了新的航迹规划算法。该算法在动态规划思想的基础上通过动态调整各个惩罚因素之间的比例关系，解决了巡航导弹在威胁条件下优先规避威胁区域和充分利用局部地形信息寻找地形掩护飞行的要求，生成了满足巡航导弹中制导阶段的要求航迹规划结果。经过实验仿真证明，该算法具有收敛速度快和计算量较小的优点。

Trajectory Programming Algorithm for Cruise Missile Guidance

Cruise missile is a new precision beating weapon in mo de rn wars and plays important roles. Effective route programming can ensure that t he missile arrives the attract area so the probability of beating will be improv ed. The study of the trajectory programming algorithm for the cruise missile is important for national defense. This paper introduces some algorithms for trajec tory programming and methods for modeling anti-flight especially for the cruise missile. And then a new algorithm based on dynamic programming algorithm is bro ught forward. The new algorithm pays more attention to the special characteristi cs of cruise missile and uses information of threaten of anti-flight weapons an d statistical features of local terrain to make better decision of trajectory pr ogramming. Experiments show that the algorithm is useful and realizable. In real simulation environment, experiments show that the algorithm gets a better traje ctory programming result. Both threat and local terrain features are considered.
