In this paper,the follower jamming and the jamming ellipse are analyzed.After studying the jamming ellipse and combining the mathematical model of FH signal,the mathematical model of follower jamming is built.The MFSK modulation was be adopted to the FH system,and then the performance of FH-MFSK system under the follower jamming is analyzed.The simulation results show that,when the FH-MFSK system is jammed by the follower jamming,the bit error rate(BER) of FH-MFSK communication system is bigger,and the anti-jamming performance of FH-MFSK system is degradation,and the anti-jamming performance of follower jamming in the FH-MFSK system is increased obviously,when the MFSK modulation is adopted.Finally,the anti-jamming measures of follower jamming are proposed.
