Experimental results on focusing moving targets in TerraSAR-X and TanDEM-X images

• Moving targets appear in TerraSAR-X and TanDEM-X images in the form of elliptic or hyperbolic curves but they can be approximated to be lines. We present here the experimental results on refocusing moving targets directly in TerraSAR-X and TanDEM-X images. The refocusing method is developed from the Range Migration algorithm and the concept of normalized relative speed. The experimental results show that the target in TerraSAR-X and TanDEM-X images is well focused to the original shape. Motion parameters of the moving target can be further estimated thank to the pursuit mode of TerraSAR-X and TanDEM-X.
