文章提出了一种基于相干混沌移位键控信号的卫星隐蔽通信方案,并建立了系统模型,然后采用离散基带信号分析了其隐蔽性能、抗干扰性能以及相关参数的选取。理论分析和仿真结果表明使用相干混沌移位键控信号完成卫星隐蔽通信具有较好的隐蔽性和抗干扰性,为基于混沌调制技术的卫星隐蔽通信提供了理论支持。
In this paper, a covert chaotic shift keying signal based satellite covert communication scheme is proposed, and a system model is established. Then the discrete baseband signal is used to analyze its concealment performance, anti-jamming performance and the selection of relevant parameters. The theoretical analysis and simulation results show that the covert chaotic shift keying signal can be used to complete the concealed satellite communication and the anti-jamming performance, which provides theoretical support for the satellite covert communication based on the chaos modulation technology.
