低空突防模型建模的研究

Low Altitude Penetration Model for Modern Fighter Planes

在现代低空突防技术中,飞机根据数字地图提供的地形数据和获得的战场态势,结合任务计划以及自身的机动性能约束条件利用航迹算法提供最优航迹,其中航迹规划包括预规划和实时重规划。预规划阶段在预知威胁转化的基础上,利用规划算法计算出航迹;在航迹预规划的基础上估算了飞机的起飞时间;在实时重规划阶段,将突发威胁等级评估与规划系统进行了集成。

In modern low altitude penetration technology, aircrafts make use of fight path algorithm to create optimization path according to terrain data stored in the digital map and obtained situation of battlefield. And then fight path control system makes aircraft to follow the optimization path. The treatment of threat in the path programming was researched including the transforming of foreseen threat and previously unknown threat which had been evaluated by threat level assessment model. At last fight path was provided by programming algorithm; on the base of path planned in advance, the flying-off time was estimated.
