- W3133040518 abstract "For ultra-high resolution spaceborne spotlight synthetic aperture radar data processing, an imaging algorithm is proposed in this paper, which takes into account the variation of the effective velocity caused by the curved orbit. First, an airborne SAR one-step motion compensation (MOCO) method is performed to compensate for the errors introduced by the curved orbit. Then, an azimuth decompression filter is utilized to separate the rang-focusing and the azimuth-focusing after a modified Stolt interpolation. Finally, a residual range cell migration correction (RCMC) and the azimuth compression are implemented successively, considering the range dependence of the effective velocity. Simulation results confirm the effectiveness of the proposed algorithm." @default.
