It is potentially useful to perform deception or cover jamming using the rotating angular reflectors. Inspired by the coherent jamming and micro-motion modulation, a novel active method is proposed for Inverse Synthetic Aperture Radar. 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. The jamming principle, key parameters and the jamming effect are discussed. The simulated data verify the effectiveness of the jamming method.
