摘　　要：联合战术信息分发系统（joint tactical information distributionsystem,JTIDS）是集通信、导航和指挥于一体的战术C3I（command,control,communication and intelligence）系统。通过建立JTIDS信息传输模型,从分析系统误码率入手,主要研究了干扰情况下采用R-S编码对系统抗干扰性能的影响。通过仿真得出多频点干扰情况下有无R-S编码的误比特率曲线图,仿真结果验证了理论分析的正确性。Joint tactical information distribution system（JTIDS） is a tactical C3I system intergraded communication, navigation and command. The information transmission model of JTIDS is established in this article. Starting with the bit error rate （BER） of the system, the influence of R-S coding on the anti-jamming performance is mainly studied in case of interference. Finally the paper obtains the figures of the BER with R-S coding and without R-S coding under multi-frequency interference, and the simulation results have an agreement with the theoretical analysis.
