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.
