航空激光/射频通信网络技术研究进展

目前航空平台间大多采用传统射频数据链进行信息传输,但是射频数据链存在传输速率低、频带资源受限和易受干扰、易截获等明显不足,无法满足空天安全、远程作战及指挥控制等军事领域对于数据信息安全高速传输的要求。航空平台间光通信具有高速率、大带宽、抗干扰、保密性好、终端小型化等特点,在空间信息可靠高速传输方面具有显著优势,不仅能够降低航空平台对地面指挥控制中心的依赖,而且有效改善传统机间射频数据链在带宽、抗电磁干扰及隐身传输等方面的技术劣势。利用航空光/射频协同通信技术实现未来机间高速数据传输,构建互联互通和信息共享的航空信息网络,是未来远程远海作战信息支援系统的重要研究领域和发展方向。

An Advance in the Field of Aeronautical Laser/RF Communication Network Technology on Research

At the moment, information transmission is mostly transmitted by adopting the traditional RF data link among the aviation platforms. Whereas the RF data link remains a lot of the problems that transmission rate is low, RF resource is limited and easy in interference, and easy to be intercepted. Such inadequate resources are hardly to meet the needs of the development of space exploration, the high speed transmission, the interconnection and sharing of the spatial information transmission and the expanding application in the military field. and development demanding to the high speed data transmission and information security of the aviation platform. Therefore, by using the characteristics of the aviation platform in the aspects of information acquisition, transmission and distribution, a high speed transmission, a safe and reliable air platform communication link is established, and the networking application of the aviation platform is further realized, which is the basis for ensuring the safe and reliable transmission of the spatial information network data. high speed transmission of data information in military fields such as air space security, long range combat and command and control. Optical communication among aviation platforms is characterized by the high speed, large bandwidth, anti interference, good confidentiality, miniaturization of terminal, and so on. Such an optical communication has advantages in reliable transmission of aviation platform and military confidentiality applications,and can not only break through the restrictions of ground command and control center on aviation platform, but also effectively improve the technical disadvantages of traditional RF data links in bandwidth, anti electromagnetic interference and stealth transmission. The mentioned above subject is an important research field and development direction of future spatial information network to use aviation optical communication technology to realize high speed data transmission between machines in the future, and to construct aviation information network with interconnection and information sharing.
