强生存条件下的飞行器变权重航迹规划研究

Variable Weight Theory Based Aircraft Path Planning for High Survival Capacity

在防空系统日益完善的信息化战场,利用常权代价函数进行航迹规划所得的可飞航迹已经逐渐不能满足飞行器的强生存力要求。运用变权综合理论改进了传统的常权代价函数,在仿真中结合微分进化算法,给出了常权航迹规划和变权航迹规划的结果并进行了分析,得出基于变权理论的航迹规划可以改善飞行航迹的生存力,提高飞行器战场生存性能的结论,仿真结果也表明该方法的可行性。

With the continuous development of air defense system in information battlefield,the path obtained by constant-weight cost function has great deficiency in aircraft survivability. Thus we improved the traditional constant-weight cost function with variable weight theory. In simulation,the results of path planning based on the constant weight and variable weight cost function were analyzed with Differential Evolution Algorithm（ DEA）. The result proves the feasibility of the path planning method based on variable weight theory,and shows that it can greatly improve the aircraft battlefield survivability.
