摘　　要：研究巡航导弹优化制导问题,由于实现低空突防,导弹要处在雷达的盲区。针对巡航导弹低空突防的特点,为了提高战场生存能力以及作战效能,可以跟随地形的起伏改变飞行高度,提出了一种实用快速的地形跟随曲线生成算法,引入地形熵的概念,实现对地形的分类,减少地形波动对地形跟随曲线生成的影响,并使用改进的曲率平滑算法实现地形跟随曲线的计算。对巡航武器系统进行仿真。仿真结果具有重要参考价值与现实意义,并已于某型空射导弹中段制导系统中得到应用。Cruise missile is a new precision beating weapon in modern wars. In order to improve field survival probability and operational efficiency, a practical and rapid curve generation algorithm for terrain following was proposed based on the improved curvature smoothing algorithm. By using the terrain - entropy, it can categorize the terrains and eliminate curve＇s perturbation caased by the waving of terrains. The algorithm is useful to the development of the warfare simulation and cruising armament. It has already been applied in the research of midcourse guidance of air launched missile.
