Performance Analysis of Satellite Covert Communication Based on Multi-Satellite Collaboration

Satellite communications with seamless global coverage play an indispensable role in modern communications. However, the openness of the satellite transmission channel makes the signals susceptible to unauthorized interception, which poses a serious security risk, especially in the field of national defense and military applications. There is a critical demand for highly reliable covert communication systems. This paper, based on the architecture of multi-satellite cooperative, multi-antenna user terminals from the covert communication theory, investigates the covert performance of satellite-based covert communication systems in a multi-satellite cooperative framework. Integrating theoretical derivations with simulation-based analyses, this study provides research results with significant reference value for satellite covert communication engineering applications.
