随着智能化技术和无人系统技术的快速发展，智能无人集群系统跨域协同的概念应运而生并得到了广泛关注与深入研究，智能无人集群系统跨域协同技术逐渐成为世界各国抢占无人系统技术竞争中的制高点。本文从我国智能无人集群系统跨域协同技术的发展需求出发，梳理了海空、空地以及海陆 / 海陆空等典型无人场景跨域协同技术的研究现状；深入分析了智能无人集群系统跨域协同技术的发展现状、技术需求以及未来的重点研究方向。最后，从总体思路、体系架构、理论创新和技术攻关 4个层面，提出了推动智能无人集群系统跨域协同技术稳健与快速发展的对策建议，以期促进我国无人系统应用能力的持续提升。

As intelligent technologies and unmanned systems develop rapidly, the concept of cross-domain cooperative technology of intelligent unmanned swarm systems has emerged, received widespread attention, and gradually become the high ground in the competition of unmanned system technologies among countries worldwide. Based on the development demand for the cross-domain cooperative technology of intelligent unmanned swarm systems in China, this study summarizes the research status of the cross-domain cooperative technology in typical unmanned scenarios such as sea–air, air–ground, and sea–ground/sea–ground–air, and thoroughly analyzes the current status, technological demand, and key research directions of the technology. Additionally, countermeasures and suggestions are proposed to promote the steady and rapid development of the cross-domain cooperative technology from the perspectives of overall concept, system architecture, theoretical innovation, and technological breakthroughs, with the aim of facilitating the sustained development of unmanned systems in China.
