Single Channel SAR Deception Jamming Suppression via Dynamic Aperture Processing

This paper proposed a novel algorithm to suppress the deception jamming against the single channel synthetic aperture radar (SAR), which provides an effective and economic way to improve the anti-deception-jamming ability of the conventional SAR system. The dynamic apertures are employed to provide multiple observations about the time-frequency distributions of the deception jamming and real echoes. The amplitude loss in different dynamic apertures is modeled to formulate the optimization problem for deception jamming suppressing. Super-resolution scheme is also involved to tighten the feasible region of the problem. The effectiveness of the proposed algorithm is verified by simulation.
