Two-Element Retrodirective Cross-Eye Jamming Based on Digital Coding Metasurface

Cross-eye jamming is one of the most effective countermeasures against monopulse radar, demanding precise cooperative control of jamming signal direction, amplitude and phase. In this paper, we propose a novel two-element retrodirective cross-eye jamming scheme based on digital coding metasurface and derive the corresponding metasurface retro-reflector model. By employing metasurface-based retrodirective reflectors, directional, amplitude, and phase modulation of the jamming signals can be achieved. Compared to conventional techniques, the proposed method offers significant advantages in both cost-effectiveness and control flexibility. Simulation results confirm the effectiveness of the proposed method.
