The invention discloses a limit alarm curve calculation method based on a terrain following model, and the method comprises the steps: firstly carrying out the terrain following track planning according to digital terrain data, then constructing a basic motion model and a collision model of an airplane, and building a corresponding alarm method through the flight state of each planned track point. A series of limit alarm points are obtained according to the obstacle avoidance operation process when the alarm is triggered, and finally a complete limit alarm curve is obtained through a fitting method. The algorithm can effectively give an alarm and give a reasonable limit collision avoidance scheme.

    本发明公开了基于地形跟随模型的极限告警曲线计算方法,该方法首先根据数字地形数据进行地形跟随航迹规划,然后构建飞机的基本运动模型和碰撞模型,利用每个规划航迹点的飞行状态建立对应的告警方法,对于触发告警的情况根据避障操作过程得到一系列极限告警点,最后利用拟合方法得到一条完整的极限告警曲线。该算法能有效发出告警并给出合理的极限避撞方案。
