Discrimination and suppression of full-polarization repeater decoy jamming in forward-squint PolSAR

For time division polarization measurement, in this paper, a novel anti-jamming method against the full-polarization repeater decoy jamming is proposed in forward-squint Polarimetric Synthetic Aperture Radar (PolSAR). According to the differences between real target and decoy in polarization domain, a new phase compensation method based on classical range-Doppler imaging algorithm is studies, and a comprehensive electronic counter countermeasure (ECCM) scheme is presented. The anti-jamming method proposed in this paper is available for discrimination and suppression of the full-polarization repeater decoy jamming. Its validity is proved by the theoretical analysis and simulated experimental results.
