It has become a key trend of unmanned cluster systems anti-jamming technology to realize efficient and reliable information transmission through the cognition of complex electromagnetic interference environment and the use of intelligent decision-making strategy. The intelligent anti-jamming communication technology in wireless communication system is discussed, including multi-dimensional spectrum sensing, intelligent sensing data fusion, spectrum monitoring data fusion and distributed decision making in interference environment. A practical UAV swarm anti-jamming communication system model is proposed. The real-time anti-jamming decision-making process and frequency hopping pattern generation are expounded.
