Abstract
- The motion of targets is well known to result in their defocusing and displacement in SAR imagery, but detection of motion and re‐focusing of targets under generic conditions remains an ongoing interest. One class of methods involves forming images of sub‐apertures in which motion defocusing will be reduced. In this paper, dynamic tomographic image formation methods utilising an optical flow constraint is used to form a video of SAR sub‐aperture images. These retain fine resolution of the full aperture, focusing along‐track motion. [ABSTRACT FROM AUTHOR]
