Integrated Sensing and Communication System Based on Space-Time Coding Metasurface
2025-03-07
Researchers propose an integrated sensing and communication (ISAC) system based on a space-time coding metasurface (STCM). The system uses the STCM to simultaneously control the propagation direction of the fundamental frequency wave for communication and generate spatially distributed harmonics for wireless sensing. By adjusting the STCM's coding pattern, the system can sense the direction of arrival (DOA) in real-time and autonomously configure the coding pattern to establish a reliable communication link. Experimental results validate the feasibility of the system, achieving simultaneous wireless sensing and communication without mutual interference.
