摘要: 为进一步提高卫星信号的隐蔽性能，该文结合加权分数阶傅里叶变换(WFRFT)的星座混淆特性与混沌映射轨迹的抗截获特性，提出一种基于物理层安全的双极化卫星联合调制方案。借鉴“相位扰码”思想和“联合设计”理念，通过扩展4-WFRFT加权项参数，增加了卫星信号处理的多样性，在此基础上嵌入Logistic映射加密，提高了信息破解的难度。建立双极化卫星混沌安全传输系统模型，提出基于MP-WFRFT一体多维的组合隐蔽新概念，探索双极化卫星信号星座优化设计和裂变融合机理。仿真结果验证了所提方案的有效性。Abstract: To improve further the concealment performance of satellite signals, combined with the constellation confusion characteristics of Weighted FRactional Fourier Transform (WFRFT) and the anti-interception characteristics of chaotic trajectory, a dual polarization satellite joint modulation scheme based on physical layer security is proposed. Referring to the idea of phase scrambling code and the concept of joint design, the diversity of satellite signal processing is increased by expanding the weighted term parameters of 4-WFRFT. On this basis, logistic mapping encryption is embedded to enhance the difficulty of information cracking. The chaotic secret transmission model of secure dual-polarized satellite communication system is established, a new concept of integrated multi-dimensional concealment based on MP-WFRFT is proposed, and the optimal design and fission mechanism of dual-polarized satellite signal constellation are explored. Simulation results verify the effectiveness of our proposed scheme.
