Joint Radar and Communication Empowered by Digital Programmable Metasurface

Digital programmable metasurfaces (DPMs) can dynamically modulate electromagnetic waves in space, time, and frequency domains with powerful capabilities. In contrast, joint radar communication (JRC) is an important avenue to use the universally intelligently. Hence, combining DPM JRC may produce a promising way achieve universal intelligent terminals. Herein, mechanism of extremely flexible based on proposed, which improve flexibility processing multidimensional information, endows capabilities perception, expression, cognition promote its level. Three kinds functions are explored interpret mechanism. First, encryption decryption wireless secure communications realized through DPM; second, range profile imaging accomplished by using DPM‐based biphase‐coded signals; third, detection simultaneously presented DPM. The combination greatly decreases complexity signal simplifies architecture system, promotes level
