| 摘 要： | 提出了一种利用低可探测性(隐身性)飞机RCS变化特性的航迹规划算法.根据目标RCS与雷达作用距离的关系以及简化的固定翼飞机RCS变化率模型,为以雷达为探测手段的防空系统建立威胁杀伤模型,在综合考虑生存概率和路径距离后给出新的航路威胁代价计算函数,最后采用Dijkstra算法在满足飞行约束条件下对隐身性飞机的航迹规划方法进行了大量的仿真.仿真结果表明隐身性作战飞机结合有效的航迹规划算法可以充分发挥自身低可探测性优势而达到隐蔽突防的目的.

| Abstract: | The paper presents a path planning algorithm for low observable aircraft using the mutative characteristic of aircraft's RCS(Radar Cross Section). According to the the relationship between the RCS and radar detection range and simplified rule of RCS-changes,a mathematical model of radar threats is built,and after considering the survivalbility and distance,a new function for evaluating the cost of path is given. In accordance with the flight constraints,Dijkstra algorithm is used to gain the optimal path fo... |
