Frequency hopping communication system has strong anti-jamming capability and is widely used in modern communication. Understanding the basic principles of frequency hopping communication and its anti-jamming performance under different jamming patterns can implement more effective jamming and anti-jamming in communication countermeasures. Based on an analysis of the basic principles of frequency hopping communication,Matlab/Simulink is used to simulate the frequency hopping communication system.The anti-jamming performance of the frequency hopping communication system is analyzed under three specific jamming patterns including wide noise jamming,partial band jamming and single tone jamming. Some measures to improve the antijamming performance of the frequency hopping system are proposed and analyzed.The simulation results show that the frequency hopping communication system has strong anti-jamming capability.Taking certain measures for different types of jamming can effectively improve the system's anti-jamming capability.
