Focussing dynamic single-channel synthetic aperture radar video with
optical flow-based compressive sensing
- Francis Watson
Abstract
The motion of targets is well known to result in their defocussing and
displacement in SAR imagery, but detection of motion and re-focussing of
targets under generic conditions remains of ongoing interest. One class
of methods involves forming images of sub-apertures in which motion
defocussing will be reduced. In this paper, we use dynamic tomographic
image formation methods utilising an optical flow constraint to form a
video of SAR sub-aperture images. These retain fine resolution of the
full aperture, focussing along-track motion.09 Aug 2022Submitted to Electronics Letters 10 Aug 2022Submission Checks Completed
