以ERS-1影像数据为例,介绍了利用轨道参数确定任意时刻卫星状态向量的方法,实验表明利用轨道参数确定卫星的状态矢量精度很高,该研究对于雷达影像的几何处理,以及其它相关处理都具有基础意义。%Taking ERS - 1 image data as an example, this paper introduces the method of determining the satellite status vector using orbital parameters. Experiments show that the use of satellite orbital parameters to determine the status vector is high in precision, which is fundamental to SAR image geometric processing and other related processing.
