摘　　要：介绍了一种求解防区外导弹巡航阶段 TA/TA(地形回避 /威胁回避 )问题的快速简便方法。考虑导弹飞行特点及机动能力的约束 ,利用网络优化算法、三次 B-样条曲线以及遗传算法寻找出性能指标最优的可飞行样条曲线 ;最后根据所求出的最优样条曲线给出导弹航路点。通过大量的仿真实验 ,证明该方法是可行的 ,具有快速性并适用于大范围、复杂地形和威胁环境下。This paper presents a fast and convenient method which aims at solving the subject of TA/TA in cruise stage about stand off missile. Taking account of both flight characteristic and flight maneuvering constraint of missile. The integrative usage of network optimization algorithm, cubic B Spline curve and Genetic Algorithm finds optimal and flyable curve .At the end, the flight course point is given based on the optimal curve.The algorithm has proved to be feasible and fast by a large number of simulations,being suitable for the large scope areas with complicate terrainsand threats.
