Abstract In modern warfare, the victory of electronic warfare has become one of the key factors affecting the victory of war. It is an important part of electronic warfare that high-efficiency jamming is used to interfere with enemy frequency hopping (FH) communication systems. Firstly, Simulink is used to establish models of a FH communication system, noise jamming, tone jamming, sweep jamming, and follower jamming. Secondly, performance of the four jamming is analyzed. Finally, bit error rate (BER) is used to evaluate and compare the performance of them.
