基于DDS与USB技术的通信对抗教学演示系统中软件的设计与实现

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软件的设计方案,并给出了此方案的具体实现。软件设计在侦察模块中采用一种基于FPGA的FFT-信道化电子侦察方案,在干扰模块中采用FPGA与DDS技术相结合的方案,在控制模块中采用了USB数据传输技术。该系统为通信干扰的各类教学和科研提供了一定的参考,并为寻求对跳频通信的最有效干扰方式提供了一定的依据。

Design and Realization about Software in the Demo System on Basis of DDS and USB Technology about the Communication Countermeasure for Teaching

This article introduces a kind of design options about the software in a demo system using for teaching and scientific experiments about the jamming and antijamming of communication,and gives the main realization of the option.In the design,a kind of FFT-Channelizing scheme on the basis of FPGA is using in the detecting module,and a scheme of combination of FPGA and DDS technology is using in the jamming module,and USB technology is using in the control module.The system gives some reference for the variable teaching and scientific research of communication jamming,and gives some gist for the search of the most effective jamming ways to frequency hopping communication.
