摘要：

For the low measuring accuracy of terrain height and deformation by geosynchronous synthetic aperture radar (GEOSAR) in available literatures, a new GEOSAR interferometry model is presented. This model is suitable for both high orbit SAR and low orbit SAR, and the mathematical expressions of the accuracy of absolute height, relative height and change detection are derived by considering the earth curve, slant range, baseline, platform height, interferometric phase and digital elevation model (DEM). The height and deformation errors in the new model are evaluated and compared with those from the simulated experiments to confirm the validity of this model. It indicates that the newly proposed model is suitable to a wider application range than Bruno's model with an accuracy of meter level.
