摘　　要：通过分析联合战术信息分发系统(JTIDS)的结构特点,建立了完整的JTIDS数据链路模型,实现了JTIDS全系统链路仿真。针对JTIDS采用扩频、跳频、冗余编码等抗干扰手段,提出了采用锯齿波调频干扰的方法,并对单载频窄带干扰和多载频宽带干扰进行了分析研究。仿真结果表明,多载频宽带干扰的效果优于单载频窄带干扰。This paper set up a whole data link model of the JTIDS by analyzing the frame of it, implemented the simulation of the entire system. Aiming at the anti-jamming means of the JTIDS such as spreading spectrum, frequency hopping and redundancy coding, proposed a jamming method using sawtooth-wave frequency modulation and analyzed the performance of single carrier frequency narrowband jamming and multi-carrier frequency broadband jamming. The result of simulation indicates that the multi-carrier frequency broadband jamming outperforms the single carrier frequency narrowband jamming.
