The Persistent Scatterer (PS) technique is a well known method for estimating object and/or surface deformation from space with high accuracy and high spatial coverage and sampling by analyzing estimation frameworks generated from stacks of interferograms [1]. It is especially suitable for urban areas which, in general, show a high density of PS to detect movements with a wide area deformation pattern...
Upcoming SAR satellite missions like TerraSAR-X or RADARSAT-2 will deliver high resolution dual channel SAR data with large coverage. These new missions - together with rising interest in area-wide traffic monitoring - motivate spaceborne GMTI as an attractive alternative to conventional traffic data acquisition. However, a moving object appears distorted in the SAR image since the well-known stationary...
