With the development of new electronic information equipment and artificial intelligence technology, the unmanned surface vehicle (USV) is becoming more important in the future sea warfare. The intelligent and integrated radio frequency (RF) sensor system will be an important development direction of USV information system. In this paper, the latest research and development trend of the USV sensor system at home and abroad are analyzed, and the future ability prospect of USV RF sensor system is proposed according to the mission and platform characteristic of USV.
