摘　　要：目前空中突防主要依赖电子干扰来降低雷达探测范围提升飞机安全性。常见的A*等航路规划算法适用于雷达探测范围交叠较小情况,但对雷达(网)航迹管理逻辑考虑不足,存在对雷达网能力衡量准确度较低、对各航路段的威胁状态评价手段缺乏等问题。针对该问题,分析了预警探测雷达(网)航迹建立、航迹跟踪及航迹丢失的基本准则,建立了一种基于马尔科夫决策的航路规划模型,并提出了基于启发式搜索的航路规划求解方法。仿真表明,该方法可提升突防兵力规避雷达网航迹跟踪的能力,并能向飞行员提供各航路段的威胁警示。Path planning methods for air penetration are mainly based on electromagnetic interference to reduce the radar detection area,such as A*algorithm for route planning.These methods are suitable for occasions with a few detection overlapping areas of radar network,but they are not accurate for the description of radar network's capability and unable to indicate the threat state along the penetration route.To address this issue,this paper analyzes the basic principles for warning radar network,casts the air penetration process as a Markov decision process(MDP),and proposes one planning algorithm based on the heuristic search.Simulation result shows that this method can not only improve the penetrating probability of air aircrafts,but also provide threat state for pilots along the penetration route.
