Data Ultra fine -Single Look Complex SAR images of RADARSAT -2 Location : Phoenix Arizona Acquisition: 4 th May 2008 and 28 th May 2008 (24 days apart) Polarization: HH Nominal Resolution [Range X Azimuth]: 3mX 3m Pixel spacing [Range X Azimuth]: 1.3m X 2.1m Bandwidth : 100 MHz Center Frequency : 5.4 GHz PRF : 1600 Swath width : 20km Bandwidth : 100 MHz Transmitted peak power: 2280 W [1,2,3,7,8]

5. Images!!

6. 40

7. Sub_Images for processing – correlation 6%

8. Pre-processing Little – speckle - slat & pepper effect – unfortunately no multiple images with different look angles Median filter Points selection

10. Coarse registration Linear shift- image2 – correlation 49.82% Image processing – geometric translation – correlation – 50.02%
