摘　　要：合理有效的飞行受限区划设是航空器规避恶劣天气进行改航策略选择的重要前提。为提高划设的实时性及充分考虑危险天气的随机动态连续变化,借助于气象预报信息,运用Matlab对图像矩阵进行处理,自动将影响飞行安全的区域边界多边形化。通过仿真分析,所提出的划设方法复杂度较低,效果令人满意,具有一定的可行性。Designing flight constrained area is an important precondition for aircraft to avoid severe weath- er and select its rerouting strategy. In order to improve the real- time of the designation and take full ac- count of the stochastic dynamic continuous change of dangerous weather, the paper dealed with the image matrix by matlab and automat- ic polygon of affected flight safety area boundary by dint of weather fore- casting infor- marion. Through simulation analysis, the complexity of designationt is low and the results is reasonable. The proposed designation is feasible.
