摘　　要：常规跳频易受跟踪干扰影响,用信道表示信息的多序列跳频系统,具有良好的抗跟踪干扰性能。为检验多序列跳频在非跟踪型干扰下的通信效果,建立了多序列跳频在AWGN信道下的传输模型,分析了多序列跳频抗干扰的原理,研究了噪声环境对多序列跳频抗部分频带干扰性能的影响。理论分析和仿真结果表明,多序列跳频在信噪比为15 dB^30 dB且为最坏部分频带干扰的条件下,误码率为10-5所要求的信干比低于常规跳频2.2 dB^2.31 dB,具有良好的抗部分频带干扰能力。Conventional frequency hopping is easily affected by follower jamming,and the multi-sequence frequency hopping system,which uses channel to represent information,has good anti-follower jamming performance.In order to test the communication effect of multi-sequence frequency hopping under non-follower jamming,the transmission model of multi-sequence frequency hopping under AWGN channel was established,and the principle of multi-sequence frequency hopping anti-jamming was analyzed,and the effect of noise environment on the performance of multi-sequence frequency hopping against partial band interference is studied.Theoretical analysis and simulation results show that under the condition of SNR of 15 dB^30 dB and worst part band jamming,the signal trunk required by bit error rate 10-5 is 2.2 dB^2.31 dB lower than conventional frequency hopping,and has good anti-part band jamming ability.
