Interactive residual synthetic aperture radar imaing
, by Rick Ottolini
The synthetic aperture radar (SAR) operator can be cascaded to iteratively estimate
satellite velocity and satellite altitude. As these parameters approach their optimal
values, the imaging operator length shrinks, thereby increasing computation speed. A 256
sample-squared operator on a joint Convex-Sun setup takes two seconds to compute and
display. The residual imaging program was adapted to Stolt migration imaging with minor
changes and a similar performance.
