Discussion on Network Communication Technology of Unmanned Cluster

Centering on the practical problems faced in the design of large-scale unmanned cluster network in battlefield environment, such as mobility management, resistance to complex electromagnetic interference, non-visible links, and severe Doppler shift, combined with the new technologies gradually mature in the field of communication in recent years, The whole-domain access mechanism of unmanned cluster is studied, and the mobility management and beam recovery mechanism based on millimeter wave are proposed, and the transmission mechanism of UAV formation based on multi-beam NOMA is proposed to provide high throughput and anti-interference intermachine link between clusters. At the same time, in view of the influence brought by the ultra-high speed movement of unmanned cluster, and the modulation technology based on OTFS is proposed to solve the Doppler shift effect problem. Finally, according to the application requirements and technical characteristics, the development trend and research direction of unmanned cluster networking communication technology are pointed out.
