摘　　要：在军事对抗中,为干涉对方的通信系统,可能需要人为制造并释放干扰信号,其中主要采取扩频技术、加密技术、猝发通信技术等.文中采用SystemView仿真软件进行信号仿真.通过仿真软件,学员可以看到信号的流向、波形和频谱,让抽象的信号形象化、具体化.基于SystemView软件对利用直扩技术的信息在发送端和接受端的波形、频域进行仿真,通过对比扩频前和扩频后的信号以及扩频后和解扩后的信号在波形和频谱上的区别,能让学员直观地感受信息在发送与接受过程中的变化.signal visualized and concrete.Based on SystemView software,the waveform and frequency domain of the information using direct spreading technology are simulated at the sending end and the receiving end.By comparing the signals before and after spread spectrum,as well as the difference between the waveform and spectrum of the signal after spread spectrum and despreading,students can intuitively feel the changes in the process of sending and receiving information.
