中文摘要
针对新时代条件下国家对卫星隐蔽通信的迫切需求,本课题拟开展高低轨卫星协同隐蔽传输的新方法和新技术研究,从提升信号的可靠接收能力和降低侦听方的检测能力两个方面提升隐蔽传输能力。首先开展隐蔽信号的可靠接收技术及信号的多维随机扰乱技术研究,提升信号自身的隐蔽传输能力;接着研究随机动态噪声产生技术,通过人工噪声干扰,降低侦听方发现信号的能力;在此基础上,研究基于人工噪声辅助的协同隐蔽传输技术,在信息速率、带宽、突发时间等约束条件下,探索协同隐蔽传输的信道容量上限。研究成果拟将隐蔽信号被检测概率降低40%。最后形成一套完整的高低轨卫星协同隐蔽传输设计理论及应用方案,为面向卫星的隐蔽信息传输提供理论指导和技术支撑,提升卫星隐蔽通信能力。
英文摘要
In order to match the urgent national need of satellite covert communication in the new era, this project intends to carry out research on new methods and technologies for cooperative covert transmission of high and low orbit satellites, where the covert transmission is promoted by improving the reliable reception ability at the legitimate receiver and degrading the detection ability at the eavesdroppers. Firstly, to improve the covert transmission capability of the signals themselves, we study the reliable reception technology for covert signals and the random multi-dimensional disturbance technology. Then the random dynamic noise generation technology is investigated to degrade the detection ability at the eavesdroppers. On these bases, the artificial noise assisted cooperative transmission technology is studied, and the upper bound capacity of cooperative covert transmission is explored under the constraint of information rate, bandwidth and burst time and so on. The research results aim to reduce the detection probability for 40% compared to the non-cooperative covert transmission.scheme.Finally, a complete set of cooperative covert transmission design theory for high and low orbit satellites and application scheme are formed. The research results provide theoretical guidance and technical support for satellite covert transmission, as well as enhance the satellite covert communication capability.
