Problems of surface change detection based on SS-InBSAR

SS-BSAR comprises of a space borne transmitter moving relative to an observed surface and a stationary receiver on the ground. Interferometric SS-BSAR (SS-InBSAR) contains two spatially separated receiving antennas and appropriate channels. SS-InBSAR can be used for a number of remote sensing applications and in particular for surface change detection. The SS-InBSAR CD compares two consecutive InBSAR images to detect changes in the earth's surface. This is done by calculating the decorrelation between the two images. This can lead to decorrelation between images in SS-InBSAR CD even when there is no deformation of the acquired surface. This paper reports methods and results of the decorrelation investigation for SS-InBSAR.
