Abstract: To meet the requirements of cross-platform network centric warfare, this paper aims at the mac-ro-requirements of wireless network at sea. Combined with the development results of current wireless network technology, spectrum sharing, aperture synthesis and radar communication, a framework of self-organizing ubiquitous wireless network with radar communication is proposed in the paper. In addition, the network framework from network architecture and topology, terminal access capability, directional networking technology, resource allocation, QoS management and network security is analysed. Finally, technological challenges, possible ways of realization and expected effectiveness of radar communication networks are given.
