SAR Processing Algorithm with Built-In Geometric Correction
Synthetic aperture radar (SAR) systems onboard small aircrafts suffer from trajectory deviations and instabilities of antenna orientation. These kinds of motion errors lead to significant geometric distortions in SAR images. In order to correct the distortions, we propose a time-domain multi-look...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Synthetic aperture radar (SAR) systems onboard small aircrafts suffer from trajectory deviations and
instabilities of antenna orientation. These kinds of motion errors lead to significant geometric distortions
in SAR images. In order to correct the distortions, we propose a time-domain multi-look stripmap SAR
processing algorithm with built-in geometric correction. In the algorithm, the azimuth reference functions
and range migration curves are designed to produce SAR images directly on a correct rectangular grid
on the ground plane. The proposed technique has been successfully tested by using a Ku-band airborne
SAR system installed onboard light-weight aircraft. |
