Unmanned clusters have distributed characteristics, advantages such as low single machine cost, fast response speed, flexible deployment, and collaborative execution, and have broad application prospects in the military and civilian fields. Intelligent communication and navigation technology is the foundation and key for unmanned cluster systems to carry out tasks, but there are still risks and challenges such as low communication speed, weak anti-interference ability, limited network topology, and heavy reliance on satellite navigation. This article focuses on the application requirements of intelligent communication and navigation in autonomous collaboration of unmanned clusters, analyzes and summarizes the current development status of ultraviolet communication technology at home and abroad, and focuses on the advantages of high communication speed, strong anti-interference ability, strong communication locality, good confidentiality, and flexible cluster networking of ultraviolet light scattering communication technology applied in unmanned clusters. A prototype of a multi unmanned platform communication and positioning integrated system based on this technology is designed and built, and outdoor real-time communication experiments are carried out to verify the feasibility of the system prototype.
