摘　　要：介绍了一种用于通信干扰与抗干扰教学与科研实验的演示系统中硬件的设计方案,并给出了此方案具体的实现。系统在侦察模块中采用A/D采样芯片与FPGA芯片相结合,在干扰模块中采用FPGA与AD9854芯片相结合,控制模块中采用计算机与USB芯片相结合的方式,实现了在计算机控制下对跳频通信进行实时侦察和多种干扰的演示功能。This article introduces a kind of design options about the hardware in a demo system using for teaching and scientific experiments about the jamming and anti-jamming of communication,and gives the main realization of the option. In the system,a combination of the A/D sampling chip and FPGA chip is used in the detecting module,and a combination of FPGA and AD9854 chip is used in the jamming module,and a combination of computer and USB chip is used in the control module. And the system realizes the demo function that it can detect quickly and make several jamming to frequency hopping communication on the control of the computer.
