Abstract

One of the applications of synthetic aperture radar in oceanography is the study of ocean surface currents by airborne along-track interferometric SAR (along-track INSAR, ATI). There is undoubted evidence that ATI enables studies of moving processes and can give an estimate of target velocities. This paper discusses experimental and theoretical concepts for processing ATI data very accurately. Furthermore, it shows that the proposed remote sensing technique for accurate measurement of ATI phase generated from ocean surface currents is promising in terms of accuracy and spatial resolution
