摘　　要：以Matlab/Simulink为平台,对无人机测控链路的相关干扰进行建模与仿真。利用Simulink通信系统仿真工具箱,对链路的发射端、接收端、信道和第3方干扰机进行了系统的搭建,模拟了测控链路的整个工作过程,仿真了在动态的相关干扰情况下链路的性能。结果表明,接收端最终的输出与干扰机发射的数据基本一致。在非合作条件下,干扰机在特定情况下能够牵引测控链路目标接收机的伪码跟踪环,阻断测控链路的正常工作。Taking Matlab/Similink as a platform,this paper performs modeling and simulation to the correlation jamming of unmanned air vehicle（UAV）tracking telemetring and command（TTC）link,uses Simulink communication system simulation toolbox to build up transmitting end,receiving end,channel and the 3rd-party jammer systematically,simulates the total operating process of TTC link,simualtes the link performance under the circs of correlation jamming.The result shows that the ultima output of receiving end is basically consistent with the data transmitted by jammer.Under the conditions of non-cooperation,the jammer can boot pseudo-code tracking loop of target receiver in specific situation and block up the normal operation of TTC link.
