Abstract :
Differential interferometry (D-InSAR) for spaceborne bistatic SAR is studied. According to advantages of the system, particularities and superiorities of D-InSAR based on spaceborne bistatic SAR are discussed first. Then, solid baseline is decomposed and the model of "three-pass" D-InSAR is established. Afterwards, the theory of data fusion is introduced to D-InSAR and a new method is put forward to avoid the max detection error. A simulation experiment accompanied by very good result is shown in the end.
