摘要

以中低轨道卫星为应用背景

对基于星载雷达高度计的卫星自主导航系统展开研究

着重分析了雷达高度计卫星自主导航中的关键因素

即地形起伏对导航精度的影响。根据实际地形的统计特性

并结合导航精度仿真分析的需要

建立了模拟地形的数学模型;对不同地形条件下雷达高度计卫星自主导航系统的导航精度进行了仿真研究

分析了不同的地形条件对雷达高度计卫星自主导航精度的影响。研究的结论对雷达高度计自主导航技术的实际应用将具有重要的参考价值。

Abstract

Autonomous navigation system based upon space borne radar altimeter applied to LEO or MEO satellite are studied

focused on the influence of hypsography on the precision of satellite autonomous navigation.Hypsography model is established based on statistical characteristics of actual hypsography;simulations are researched on to analyze the precision of autonomous navigation under different hypsography conditions.Reference for the application of autonomous navigation is presented by using radar altimeter.
