OCTAVE DIVISION MOTION COMPENSATION ALGORITHM FOR NEAR-RANGE WIDE-BEAM SAR APPLICATIONS

By H. Wu and T. Zwick

Full Article PDF (265 KB)

Abstract:
The space-variant motion errors are speci c to different targets and proportional to the beamwidth of a synthetic aperture radar (SAR) system, which makes them very difficult to be compensated for a SAR system with wide beamwidth. In this paper, a motion compensation (MoCo) algorithm that exploits the features of the geometry of near-range SAR applications is proposed. By dividing the whole range swath into several octave sub-swaths, the effects of space variant motion errors can be greatly reduced, especially for targets at nearer range, with low computational load.
