Abstract: The multi-manned-unmanned joint system has been regarded as an important part of the future intelligent warfare system. To improve the self-organizing transmission capabilities of the mission-driven manned-unmanned combat systems, typical air-ground collaboration scenarios such as cities, jungles, and mountains are sorted out, and research aspects including the deployment of link construction, coalition command structure, coordinated spectrum sharing, multi-mode data transmission, etc., are discussed. The joint deployment of link construction guarantees the interconnection of multiple nodes in the system. The coalition command structure supports the division and combination of systems driven by tasks. Coordinated spectrum sharing realizes resource coordination between di erent coalitions and spectrum access within coalitions. Multi-mode data transmission provides flexible cooperative transmission methods of manned-unmanned systems. Facing the challenges of complex battlefield environment and spectrum situation, the distributed, robust, dynamic adaptability, and scalability optimization requirements of the air-to-ground manned-unmanned communication system transmission are elaborated. Finally, potential oine learning methods and online perception decision-making optimization methods for manned-unmanned communication systems are analyzed.
