Experimental result for SAR GMTI using monostatic pursuit mode of TerraSAR X and TanDEM X on Staring Spotlight images
TerraSAR X and TanDEM X is able to fly in monostatic pursuit mode, a formation with the satellites in identic orbit displaced in along track of a distance corresponding to 10 s delay. Such formation gives e.g. the ability to detect very slow targets or targets moving only between measurements. This can be performed using Change Detection (CD) and/or the Detection of Moving Targets by Focusing (DMTF) technique. A combination of DMTF and CD is promising. To investigate the applicability of the methods for moving target detection, an experiment was performed with TerraSAR X and TanDEM X in monostatic pursuit mode and several deployed targets.
