Robust Two-Dimensional Spatial-Variant Map-Drift Algorithm for UAV SAR Autofocusing
Autofocus has attracted wide attention for unmanned aerial vehicle (UAV) synthetic aperture radar (SAR) systems, because autofocus process is crucial and difficult when the phase error is spatially dependent on both range and azimuth directions. In this paper, a novel two-dimensional spatial-variant...
