【Abstract】 Space-air-ground integrated networks(SAGINs) serve as a crucial infrastructure for achieving global communication and ensuring seamless network connectivity. In future high-interference environments, maintaining the effectiveness and reliability of data transmission within SAGINs is of paramount importance for national security. This paper explores potential applications and key techniques for anti-jamming in both the time-frequency and spatial domains, tailored to the adversarial nature of the operating environment in SAGINs. Additionally, a comprehensive analysis of anti-jamming strategies in SAGINs is presented. The paper concludes with insights into future developments, aiming to provide directional guidance for further research and practical applications.更多还原
