摘　　要：以地形跟踪 /地形回避为基础 ,提出了用轨迹的侧向仰角代替航迹的高度作为航迹规划的隐蔽性代价的概念 .该方法结合航迹的航程代价和飞行器的各种机动能力约束 ,可以达到对已有航迹的优化作用 ,同时也可直接进行简单的控制点航迹规划 .仿真研究结果表明 ,该算法满足飞行器飞行的各种条件 ,是一种可行方法 ,该方法速度快、规划出的航迹可以有效提升飞行器在飞行过程中的生存能力 ,可以在用于任务规划的同时 。An algorithm for the optimization of the vertical flight path by using cover up ability as its main cost was presented. Based on the algorithm of TF/TA, the flight path height was replaced by side pitching angle to measure the cost of cover up ability of the layout flight path. By combining the sail cost of the flight path and several mobility restrictions of the aircraft, the algorithm can be used to optimize the layout of the flight path, and perform the layout of the simple flight path based on the reference points. The simulation result showed that the algorithm could satisfy kinds of flight conditions of the aircraft and raise the aircraft′s viability during the sailing process. It can be used to optimize the flight path after task layout.
