| Abstract: | The traditional formula computing the synthetic aperture length of spotlight SAR and its localization are presented in this paper firstly. Then the new formula to com puting the synthetic aperture length of spotlight SAR is deducted on the basis of airborne and spaceborne geometry models. Especially in spaceborne model, the earth speed is considered. Finally, the data simulation results validate that it is necessary to use the newformula to compute the synthetic aperture length. This paper provides the reference for deagnmg synthetic aperture length of spotlight SAR. |
