Jamming of Inverse Synthetic Aperture Radar Imaging using Time-modulated Metasurface

In this paper, a method for inverse synthetic aperture radar (ISAR) imaging jamming using time-modulated metasurfaces is proposed. This method interferes with ISAR imaging by temporally modulating the metasurface to achieve phase modulation of the incident wave in the fast time or slow time direction. The effectiveness of the time-modulated metasurface in jamming of ISAR imaging is verified by electromagnetic simulations for the first time, taking a square metal plate covered with a time-modulated metasurface as an example.
