摘　　要：联合战术信息分发系统(JTIDS)作为Link-16数据链的数据终端,具有用户多、容量大、保密性好、抗干扰能力强和功能多等特点。首先,研究了JTIDS系统地空信道模型及其链路性能。然后,在地空信道特性分析基础上,针对JTIDS系统特点,按照空中平台飞行状态准确建立对应信道模型。最后,结合相关文献的实测数据,对JTIDS系统的链路性能进行了仿真分析。仿真结果表明,该信道模型及性能分析结论有助于JTIDS同类数据链系统的设计与完善。Joint tactical information distribution system （JTIDS） is used as the data terminal of Link-16. It has characteristics of multiple access, large capacity, good security, high anti-inter- ference ability, and multi-functions. The air-ground channel modeling and the link performance of the JTIDS system are researched. Aimed at characteristics of JTIDS, corresponding channel models are established according to different states of the aircraft. The performance of JTIDS system link is analyzed with measured data given by the related literatures. Simulation results show that the channel model and the performance analysis can contribute to the design and the improvement of the data-link system like JTIDS.
