Abstract: | The usual analyses of the effect of constant radar velocity error on synthetic aperture radar (SAR) focus generally yield the result that the cross-radial component of velocity error is primarily responsible for image defocusing. A simple argument is given demonstrating that image focus depends on accurately estimating radar speed, in which the along-track (AT) component of velocity error is most important. |
