| 针对大中型无人战斗机（Unmanned Combat Air Vehicle, UCAV）在中空环境下抵抗攻击和生存能力弱的问题，本文研究一种箔条干扰弹投放策略优化算法。该算法以发现概率为评估指标，在一定发现概率范围内寻求每个时隙下箔条干扰弹的最优投放策略。研究旨在尽量推迟UCAV被发现的时间，甚至实现全程都未被察觉，从而节省资源损耗，提高UCAV的生存能力和任务成功率。首先，建立箔条走廊掩护场景模型和发现概率模型；随后，形成时隙特定的箔条干扰弹数量最小化问题，并提出相应约束条件；最后，深入分析优化问题，结合数学分析方法，对最小化问题进行求解，得到每个时隙下的箔条干扰弹最优投放策略。仿真结果表明，所提出方法能够在降低发现概率的同时，减少我方作战资源的消耗，具有有效性和良好的健壮性。 |

| Abstract: |
| Aiming at the problem that large and medium?sized unmanned combat air vehicle （UCAV） has weak resistance to attack and survivability in a medium?altitude environment, this paper studies an optimization algorithm for the launch strategy of chaff jamming shells. The algorithm takes the detection probability as the evaluation index, and seeks the optimal launch strategy of chaff jamming shells in each time slot within a certain range of detection probability. The purpose of this study is to delay the detection of the UCAV as much as possible, and even to achieve the whole process undetected, thereby saving resource consumption and enhancing the survivability and mission success rate of the UCAV. Firstly, a chaff corridor cover scenario model and a detection probability model are established. Subsequently, the problem of minimizing the number of chaff jamming shells with specific time slots is formed, and the corresponding constraint conditions are proposed. Finally, the optimization problem is analyzed in depth, combining with mathematical analysis methods, to solve the minimization problem and obtain the optimal launch strategy for chaff jamming shells under each time slot. The simulation results indicate that the proposed method can reduce the detection probability while minimizing the consumption of our combat resources, delaying the time when the UCAV is detected by the enemy, and demonstrate effectiveness and good robustness. |
