Abstract:

It is potentially useful to perform deception jamming using the digital image synthesizer (DIS) since it can form a two-dimensional (2D) decoy but suffers from multiple decoys generation. Inspired by the intermittent sampling repeater jamming (ISRJ), the generation of inverse synthetic aperture radar (ISAR) decoys is addressed, associated with the DIS and the ISRJ. Radar pulses are sampled intermittently and modulated by the scattering model of a false target by mounting the jammer on a moving platform, and then the jamming signals are retransmitted to the radar and a train of decoys are induced after ISAR imaging. A scattering model of Yak-42 is adopted as the false-target modulation model to verify the effectiveness of the jamming method based on the standard ISAR motion compensation and image formation procedure.

Key words: inverse synthetic aperture radar (ISAR), digital image synthesizer (DIS), intermittent sampling, decoys
