| Abstract: | 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. |
