The Design And Implementation Of DRFM System

As the coherent processing technology and matched reception technology havebeen widely used in new radar systems, the traditional jamming techniques aredifficult to produce good results. Digital Radio Frequency Memory (DRFM)technique can adapt to ever-changing, fast-changing and complex signal environments.It can keep jamming signals being coherent with jammed radar signals and make goodradar jamming effect. So, DRFM has been widely used in Electronic Warfare andbecoming an essential part of modern warfare.DRFM systems do not only to achieve high-speed signal acquisition, signalplayback, but also to complete the processing of the large amouts of data in real time.So it makes high demands to the system in real time signal processing. This paperproposes a scheme based on multi-core DSP+FPGA to solve that problem.Firstly, the article does some research and analysis on the basic principles ofDRFM system. Combined with the current level of development of the semiconductorchip, we propose a scheme based on multi-core DSP+FPGA and give a detailedanalysis and demonstration. Secondly, according to the functional requirements thispaper gives the important module hardware and software design in detail andcompletes building and debugging the hardware platform. Finally, it summarizes thedesign and analyses the application foreground.
