Abstract

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.
