中文摘要：

随着民用航空产业发展,航空器流量会大幅度增长,空域资源有限性成为限制民航发展的重要因素。运用光传播模型、拉普拉斯算法对折射率地图的航迹优化问题进行研究,引入光程概念,全局考虑航空器运行时的航迹代价,即实际距离和航行难易综合评价。分别从离散、连续切入,在指定时间内,探测周围空域基本状况,高效、安全完成最优航迹确定。结果表明,利用光传播模型进行航迹优化,相比传统航迹,能更好兼顾安全和效益,实现战术层面的航迹优化。

英文摘要：

With the overall development of the civil aviation industry,the number of aircraft will surge,leading airspace to be overcrowded. In order to address this issue,this paper introduces LPA（ Light propagation model） and Laplace algorithm to optimize the trajectory. By using principle of light propagation,it not only shorts the distance in ever small scale,but avoids the dangerous areas. In conclusion,it shows that the result based on new models is far more superior than the before.
