SUMMARY:Dynamic Reconstructions in Synthetic Aperture Radar - Francis Wats
 on (University of Manchester)

UID:TALK197092@talks.cam.ac.uk
DESCRIPTION:This talk aims to help facilitate and build on discussions ini
 tiated between SAR engineers and mathematicians in the RNT programme - to 
 build a common understanding in some areas.&nbsp\; We will present the SAR
  data model which is used as the basis for image formation methods\, highl
 ight some of the assumptions and approximations this builds in (some of wh
 ich may need to be addressed in the context of Rich and Nonlinear Tomograp
 hy)\, and briefly introduce reconstruction approaches to image formation.&
 nbsp\; The main topic of the talk is the challenges and artefacts encounte
 red due to moving targets. We show how a 4D tomographic reconstruction met
 hod can be adapted for focusing along-track target motion\, producing a fi
 ne-resolution SAR video.
