| 摘 要： | 传统的地形轮廓匹配 (TERCOM )辅助导航系统 ,由于其实时性差 ,已不能满足飞行器超低空高速的导航需要。本文引入预测控制的思想 ,提出了一种基于高度特征的地形轮廓预测匹配方法 ,减少了计算量 ,提高了导航系统的实时性和机动性。

| Abstract: | The Conventional terrain contour matching(TERCOM) aided navigation system with poor real-time property,it can't meet the requirements for the navigation of aircraft in low altitude and high-speed flight.By introducing the idea of forecast control,the authors propose a terrain contour forecast matching method based on height feature.The calculation amount is reduced remarkably,and both the real-time property and the flexibility of navigation system are improved. |

| Keywords: | terrain contour matching altitude feature forecast control real-time property |
