军用无人机航路规划类型与作战任务紧密相关, 通常在执行远距离情报侦察任务时, 采用固定航路规划方法推算飞行航路。为定量分析固定航路规划的质量优劣, 发现制约航路质量提升的关键点, 建立了以任务完成度、飞行安全度和性能发挥度为主体的航路质量评价指标和计算模型。在此基础上, 以环形航路规划为例提出了一种新的固定航路规划方法, 方法以战斗分界线为基准, 经历航路逼近、前伸探索、回溯寻优3个阶段, 得出常规、激进、保守3种航路规划结果, 满足不同作战背景和任务要求下的航路规划需求。在作战仿真系统中的应用与实践表明了方法的有效性, 航路规划的质量评价能够清晰反映航路优劣, 为指挥员决策提供依据。

The type of military UAV route planning has a close relationship with combat tasks, and the fixed route-planning methods are commonly used for long-distance reconnaissance tasks. Firstly, in order to quantitatively analyze the advantages and disadvantages of the quality of fixed route planning and detect the restraining factors of the route quality enhancement, the evaluation index and calculation model of the route quality are built, whose main parts are the completion of tasks, air safety and the perforance of the functions. Then, a new fixed route-planning method is proposed taking the loop route planning as an example. The battle dividing line is taken as the reference for route creating, including the three stages of route approaching, forward exploration and backward optimizing. Three kinds of results of route planning are obtained, i. e. , conventional route, radical route and conservative route, which could satisfy the needs for different battle backgrounds and tasks. The application of it in the operational simulation system has proved the effectiveness of the route planning method, and the quality evaluation of the route planning can clearly reflect the advantages and disadvantages of the routes, which can be used as a reference for the decision-making of the commander.
