综合ＴＦ／ＴＡ是新一代低空突防技术，ＴＦ／ＴＡ最优航迹的计算是其控制系统的核心。文中提出了一种新的综合ＴＦ／ＴＡ最优航迹算法，它用动态规划和树型搜索相结合的方法，实时计算综合ＴＦ／ＴＡ最优航迹。算法考虑了飞机机动能力的约束，使最优航迹在不需要平滑处理时就是一个可实现航迹。另外还考虑了威胁的影响，使最优航迹能有效地进行威胁回避。计算结果表明，所得的最优航迹具有综合地形跟踪／回避和威胁回避的能力。
Integrated TF / TA is a new generation of low altitude penetration technology. The calculation of TF / TA optimal trajectory is the core of its control system. In this paper, a new integrated TF / TA track algorithm is proposed, which uses the combination of dynamic programming and tree search to calculate the integrated TF / TA optimal track in real time. The algorithm considers the constraints of the maneuvering ability of the aircraft so that the optimal track can be a track when it does not need to be smoothed. In addition, the impact of threat is considered, so that the optimal route can effectively avoid threat. The calculation results show that the optimal trajectory obtained has the ability of integrated terrain tracking / avoidance and threat avoidance.
