| 摘 要： | 介绍了分别采用斜装天线的雷达高度计，以及雷达高度计与其他敏感器组合实现卫星导航的基本原理。分析了三种不同的雷达高度计组合方案。研究认为影响雷达高度计自主导航精度的关键因素是地形起伏，并由此提出了一个采用雷达高度计、红外地平仪、CCD星敏感器和惯性测量组件的适于近地海洋卫星导航系统组成的设计。

| Abstract: | The general principles of the radar altimeter with inclined antenna and combination of radar altimeter and other sensors were introduced in this paper. The three different schemes of radar altimeter combination were analyzed. It was showed that the key factor that affected the accuracy of radar altimeter autonomous navigation was the terrain fluctuation. Finally, it was designed a navigation system of radar altimeter, infrared horizon, CCD star sensor and inertial measurement unit, which was suit for close-orbit ocean satellite. |
