ISAR active jamming method based on sinusoidal modulation

摘要

It is potentially useful to perform deception or cover jamming using the rotating angular reflectors since they can form deception echoes along range and azimuth. Inspired by the coherent jamming and micro-motion modulation, a novel active method is proposed for inverse synthetic aperture radar(ISAR). Radar pulses are sampled and frequency-modulated along azimuth by sinusoidal signal, and then the jamming signals are retransmitted to the radar and the jamming images are induced after ISAR imaging.Therein, the jamming principle, key parameters and the jamming effect are discussed. The simulated data verify the effectiveness of the jamming method.
