Effect caused by range curvature distinction for deception jamming under SAR imaging

The jamming imaging effect caused by range curvature distinction under synthetic aperture radar (SAR) imaging is studied. The imaging matrix model is established firstly, which is simplified for signals and jamming. And the defocusing effect is analyzed in high-accuracy imaging algorithm, caused by range curvature distinction under SAR imaging. Then a comparison between R-D and CS imaging algorithms for utilizing in the regions of various range curvature distinctions including real targets and gamming is studied. Finally, simulation experiment verifies the defocusing effect coused by active deceptive jamming in wide scenes in the high accuracy imaging algorithm, which is conductive to an improvement in electronic counter measures (ECM) to SAR.
