摘　　要：简要介绍星载SAR轨道特点以及轨道状态向量确定方法,利用Gamma软件获得一景SAR影像的粗轨和精轨数据,并在Matlab下用多项式拟合方法实现数据拟合,并给出拟合品质的好坏,表明DEOS提供的精密轨道数据对干涉处理具有较好的效果。This paper introduced the orbit characteristic and orbit state vector determination method of space-borne SAR satellite in brief.It received rough orbit data and precise orbit data of a view of SAR image using Gamma software.Then,it realized data fitting using polynomial fitting method in Matlab and judged its quality.Finally,it indicated that the precise orbit data provided by DEOS had better effect on interference processing.
