The cross-track baseline in InSAR system is very sensitive to terrain fluctuation which is widely used to retrieve the DEM. The cross-track baseline influences the coherence of the radar echoes seriously. In this paper, we analyzed the decorrelation caused by cross-track baseline and the channel mismatch respectively. And a decorrelation reduction method by means of compensating the decorrelation caused by the spatial baseline is given. Finally, simulation results verified the validity.
